I am planning on purchasing a C5 – most likely a year 1999-2001 and am looking for some answers to a few questions. I would greatly appreciate any advice from you experts.

Questions:
1) Typically when any manufacturer introduces a new body style it takes 1-3 years for the manufacturer to work out all the kinks. What is the first year that all the kinks were worked out of the C5? What are the problems that I should look for on the first couple of years?

2) Is there a web page that I can get a list of all the recalls and notices from Corvette for the years I am considering?

3) What are the big ticket maintenance items that need to occur and at what mileage. (ie. timing belt)

4) What big ticket items have failed on your car (oil pump, water pump, alternator, etc.)? What is the model year of your car, what was the mileage when it occurred, and how much did it set you back?

Are there any other things that I should consider?

I am most interested in a convertible, in Red, Yellow, or Blue with a light colored interior and top (black interiors just don’t work in TX – you burn yourself when you sit in them).

Thank you for any advice you can provide!

 

Suggest you check out the sticky at the top of the page. It is very detailed, and covers many of the questions you've asked, several you haven't, and many you should ask. Welcome to the forum!

 

I've got some Word files I can send you if you PM me your e-mail address.

So far, the big ticket items I have had repaired on my car are as follows:

- Rings replaced due to excessive oil consumption. (Fixed under warranty) Happened at about 11K miles.
- Rear differential seal leaks (3 times). (Fixed under warranty). Last time happened at about 22K miles - car now has 32K on it.
- Seal between tranny and differential leaked. (Fixed under warranty - cost to warranty company - $650). Happened at 25K miles.

All of these items fai

The differential seal leaks have been the most troublesome to get fixed obviously, but looks like they have it stopped at least for now. Been almost three years since the last leak.

I think you'll find that for the most part, the same annoying problems that happened to the early cars still happened to the later ones (referring to the column lock issue, differential seal leaks, etc).

The C5 is for the most part pretty reliable. Just check whatever car you are looking at over carefully and get a service history if you can.

 

Here something that might help you out.

All of this information was collected from the Corvette Forum message board, so do not take it as absolute gospel. However, it should be somewhat close.

This keeps appearing in these lists, but no one can ever explain what two slots they are talking about. Does anyone know what slots (or, better yet, can anyone provide pictures)?

Maybe the 2 side gill slots. Anybody got pictures to compare these on early and late model C5's? Jim
