Hi Mark:

Almost always these days, if we hear from a customer, it's to complain
about the product or service they received!  It is all too infrequent
that we get a message from the satisfied customer!

I am writing to tell you that I was EXTREMELY PLEASED with my recent
purchase of items from you for my Buick Grand National, and in addition,
your service was IMPECCABLE!!!  I don't know if you are doing this as a
part time or full time job, but I would be proud to have you and your
team working for Me! 

The seat hinge overlays are super sharp, as are the pullstrap
screwcovers; one of mine was missing and yours were the perfect
solution...and so well designed and made!  The coil pack plate as well
far exceeded my expectations!  Very sharp addition to the engine
compartment, yet subtle, so that the first people I showed it to thought
that it was absolutely factory stock!  Buick should have done it first!

Then we get to the License Plate frame... I have already had three
inquiries as to where they could get one like it!  Your cohorts did an
excellent job on that as well.  Needless to say, I am very pleased with
the whole package, and the car will probably take first place at the big
local show here next weekend!

Mark, if I can act as a reference for your products at any point in the
future, please, by all means, direct your customers to me and I will do
so.  When I get some good weather, I will shoot some photos and email
them to you...feel free to use them in your advertising.  My GN is an
'87 with 15,000 totally original miles, one owner, still in factory
paint (THERE'S A FIRST!!) and has only very slight performance mods...3"
downpipe, Hollow Cat, 2 1/2" stainless duals back to tuned Supertrapps,
big MAF, GNX chip, internally beefed trans, GNX Wheels.  Launches
straight as an arrow, and does a 12.7 1/4 mile on Eagle GT's!  Vettes,
'Stangs and Camaros always find a reason to turn off before the next
light!  An occasional Viper will get excited, but fade away after I
pace them to the first light and then light 'em up before the second
one!  The only real fun is an '89 Trans Am Turbo who comes out to play
occasionally...he is about on par with me.

Mark, stay with it...you are great to do business with!  Lyle Haws

Mark,

So far I have maxed out what I need from you.  I will continue to check you
site for new things.  I just wanted to say thank you for all of your help. 
You have put the finishing touches on my car that are hard to find.  My car
has put on a whole new look.  That exhaust motor still surprises many people
who don't know what the GN's are.  It is a blast at a cruise or next to a
V8.  Thank you so much.

Steve

These are excellent products!  I couldn't be happier!  Please continue to keep up the great work!  Great shipping, perfect emails,  I have never been so happy with a product.  Please continue the excellent work!

I received your custom console kit today and I was VERY happy with it.  The
custom work with engraving was exceptional!

Thank you,
Eric Herron

Mark:
I received the dash panels on Friday.  I am extremely impressed with them.
They were perfect in every way.  I put them on my car immediately.  Everyone
else I have shown have been impressed with them as well.  I am willing to
give a testimonial to others if you ever want me to.  I am going to take a
few pics to show you how they turned out on my car.  Thanks for your efforts
with those.

Later!, Rob Reid

Mark,
I got the stuff today. I just want you to know that they are Beautiful!! Much
better than I anticipated.  Thanks and I will definitely be doing more business with you,
Mike Moore

Hi Mark!  Just wanted to let you know that the passenger plate arrived today
in the mail.  Thanks!  I love it!  Your stuff is the best around!  You'll be
hearing from me again soon! 

Thanks again and have a great holiday weekend!
Genie

Mark, Thank you so much!
I received the custom passenger plate, and the
console kit, and the door handle set.
I got them in time, and my boyfriend loved them.
I am so happy with my purchase, and
I plan on ordering more for x-mas.

I received your custom shifter handle with engraving and it just adds a touch of class to my Grand National.  Love your products!  Please keep on making more unique products for these unique cars!
Jonathan Cruz

I would like to say that I was really
pleased with the shifter handle.
I was very happy with how easy it was to
install, I'm definitely going to be buying more!          
Thanks again for getting to me before
Christmas.

Hey Mark, I just wanted to say that your console overlays and scanmaster
hoods are BEAUTIFUL.  My father ordered them from you for XMAS and I cant
tell you how pleased I am....now only if we could get the snow and salt off
the roads so I can put the parts on my GN!!!:(  Oh well, haven't seen it in 2
months......just wanted to say thank you, and Ill be buying more parts from
you in the future!!!!!
Neil Werner

Hi Mark

Steve Adams

Just wanted to drop you a line, I received my MAF pipe today and it took me
a total of 13 minutes to install it!  An absolute first-rate product, my
deepest thanks and I look forward to doing business with you again!

Jim

Mark,

I received the dash appliqué today.  Let me just say that I am very
impressed.  It matches the original very well.  I have recommended your site
to a fellow Buick enthusiast.  Keep up the good work.

Mark,
Got my Big Mouth Cold Air Kit Installed and it went very smooth. Instructions were good and the final result is excellent. I really like the appearance and it lowered my intake air temp by more than 10 deg. In Florida that is very important. It was money well spent.

Steve Cornell

Hey Mark,

 Already installed the cold air kit when I got home from the BBQ. Made a
noticeable increase in performance and sounds awesome! Easy, quick install
too. Good doing business with you, thanks!

Erik McNeice

Hello Mark, this is a courtesy mailing to let you know that I received all of
my custom work. I will be in touch in a couple of months for some more custom work. Thanks again for offering such unique products. I will send before and after pictures when everything is finished. Everything I received today is top notch.

Hello and thanks for the prompt shipment of the tri-shield door strap pull
covers. They are very nice and I love the quality. Keep up the great work and
I plan to do business with you again soon. 
Thanks, James Wood

Mark, I have installed your cold air kit on my GN. I love it ! 
Your kit fits perfect, and really cleans up the look of my car. I have
passed on the info to my friends..All they have to do is LOOK under my 
hood!!
                                                  Many thanks,
                                                            Richard Williams

Great job!!!  I just received my dash kit and white face speedo..  They look awesome, it's changed the whole feel of the car!  I plan on sending some pics, soon!!  Thanx again!

Jason Shannon

Hi Mark,

Just thought you may like to know that your Big Mouth kit went 10.92@122.4
(at 1700' elevation) in my stock motored car a couple weeks ago. It must
work!

Thanks again!
Mike Price

From the Turbo Buick Message Board

Click here to see the whole thread! http://www.turbobuick.com/forums/showthread.php?s=&threadid=23469

Hi All;

Since the board usually has its share of negative feedback regarding vendors and products, I thought I'd share some very positive feedback with the TR community regarding Mark Hueffman's Big Mouth Cold Air Kit sold through his website - www.buickgn.com. Hopefully, this will help others make more educated decisions when comparing some of the cold air kits out there.

After trying a few different MAF pipes and looking at various cold air/ram air kits, I ordered Mark's kit and installed it recently. The quality is definitely top-notch, and Mark is always available to answer questions about installation, etc.

Once installed, the fit is excellent. It's EXTREMELY rigid and doesn't require drilling holes for brackets, etc. Though fitting it does require some patience (as does any project on these cars), there's plenty of wiggle room with the elbows and pipes supplied and you end up with more than enough clearance from alternator bolts, radiator hoses. I relocated my vapor canister about 1/2 inch towards the fender leaving one screw in place and drilling another hole for the second screw about 1/2 towards the fender. The filter sits level with the lower left air dam, and can't be seen unless you get under the car. Plus, it makes the car sound just wicked.

If anybody is interested in seeing a pic of the installation, let me know. Otherwise, I would recommend Mark's cold air kit without question. Good Job Mark!


Thanks,
Rich Cabelo

Got the (BIG MOUTH) kit installed over the weekend.  What a  difference that thing made.  I was running about 16-17 psi of boost.  I had to turn it down after I
installed the kit, it jumped up to 21psi!!  That turbo really loves all
the air its getting.  Now if I could only keep it from sucking up all
the critters I drive by on the side of the road.  I'm really gonna miss
my little dog !

---Mark,
 I received the big mouth kit today & it looks great!!!I'm just waiting on my translator I just bought so that I can hook everthing up. I appreciate the super fast shipping!!!

                      Thanks again, Thomas

Hey Mark,

       Just wanted to let you know that I installed the cold air kit I bought from you today and I am very pleased with it. The sound is nice since my car is so quiet and after a bit of finagling it slid right in there. Thanks again for making such a nice product.

Matt Burns

Hey Mark, just wanted to let you know I received my order from you the other
day and the quality of  parts is exceptional. The engraving is perfect, I
didn't know they were gonna look so good. All I can say is that you have a
quality product you can be proud of. I went right out and put them on my GN.
I'd recommend you to anybody. Keep up the good work. Thanks  Tarey D.
