: Want a Corvette Whats the difference between 94-04?
Jethrowbodene 04-15-2007, 01:21 PM I am turning 21 in Sept. I currently drive a 1994 mustang Gt vert with custom exhaust, cobra rims, and upgraded sterio. I am transfering to a 4 year school next spring. I am looking for a car that is resonably powerful to drive on the highway as my job is 25 miles from where I will be going to school. Compared to a mustang how much is a corvette for matience such as oil changes, part costs, labor compared to a mustang? I looked at the 1999 model and loved it. I want to spend 20k max. I am looking to put 8-9k down payment and loan the rest. What kind of insurance am I looking at? About model year differences. It seems like the 97-00 are the same body and motor? What is the difference? The 97 and 98 attract me to the lower price.
The determining factor will be insurance costs and matinence compared to my mustang. If I get one with 55 someK miles what can I expect to do to it between then and 100k miles on average? Thanks in advance for any info.
tstar 04-15-2007, 10:42 PM I'd have to say that this is one loaded Post!!!! I don't have explicit answers to all your questions but generally;
1. Most of us do our own routine maintenance, and is one of the reasons for this Forum.
2. I would say that parts from the dealer MIGHT be a tad more then your stang but aftermarket companies make a ton of stuff for the Vette and competion seems to keep the Corvette tax pretty much in check there...
3. Maintenance costs vary from place to place, like for any vehicle shop around. One nice thing about the C5 is that it has a Diganostic Code Reader built into the car...
I have a 99 and love it!!!! But I'm biased! I haven't really heard any horror stories about the 97s, which is a bit unusual for the first model year... Here's a run down by model year;

TSTAR - is the man to get answers. LOL you always have the answers or comment. I know who to hit up when I have a question! :D
tstar 04-16-2007, 09:51 AM Yeah that'll be the only time I won't have an answer! LOL But I'm sure I'll comment! :D
smokinvette 04-16-2007, 10:10 AM No kidding! Tim you must eat and sleep Corvettes, I'll agree you seem to always have well thought out responses to many questions on the forum! Appreciate you helping out so many!
tstar 04-16-2007, 10:22 AM No kidding! Tim you must eat and sleep Corvettes, I'll agree you seem to always have well thought out responses to many questions on the forum! Appreciate you helping out so many!
Careful! That sounded like my wife!!! lol
I've had a Vette since I was 17, alway loved em! They aren't perfect but it's the closest thing to perfection that I can afford! And I really enjoy helping out, everything I've learned, which really isn't much to be honest, I've learned from other Vetters, these Forums certainly do get the info out faster then back in the day don't they?
So I want to thank YOU for hosting this great Forum! Hats off to ya!
John H 04-16-2007, 04:44 PM Tim, very informative on the differences between years, you really answer question in a professional manner.
Quick question, I have a 98' Coupe, and I know the fuel pump noise is a pain, (usually turn up the radio, or looking to put Borla Stingers on that may help drown it out). Any other optons to relieve noise?
tstar 04-16-2007, 10:03 PM The first generation pumps spun at a higher speed and had a smaller drive gear. GM updated the pump later on (larger gear, slower speed)... in mid '98 I think, in an effort to reduce the whine.
Here's a couple of ways to help with the noise;
It helps to always try and keep your fuel tank level above 1/2, not only for noise but to keep moisture (water) from getting on the pump and to help cool the pump as well.
Cover the "wall" behind the driver's seat with a noise reduction barrier such as Dynamt or Frost King, under the carpetting of course! LOL
You can also try and stuff insulation from under the car between the fuel tank and driver's seat area... I've heard of guys doing this but have seen no pics on it, I'm not sure how they keep the insulation from falling out! :D
The only viable options in fuel pump replacements I've heard about is this kit;

Hope that helps!
John H 04-23-2007, 04:46 PM Thanks again Tim for the advice. I'm going to try the noise reduction barrier. I guess by keeping the tank above the 1/2 full point the sticker shock isn't as bad, @ $3.15 a gallon premium!
02RonZ06 04-25-2007, 07:05 PM I hope that you do not make a decision on buying by the gasoline prices... Many say that their 6 speed vettes get 28-31 MPG on the highway, there aren't many vehicles with 300-405+ HP that can do that and maintain a daily driver vehicle too.
