One minor correction that was pointed out to me, the new fuel system was installed in late '02 after the first 5 months of production.

http://www.c5registry.com/MembersOnl...2003/index.htm

My car was produced in Dec '02 and I have the new fuel system. Not nitpicking here but over half of the '03s had it.

You can look in the glove box for RPO code FFS. It was changed to comply with new emissions standards and is shared with the XLR and newer Corvettes. The design may have carried forward to the C6 but this was just to comply with more regulation, not to make it better for you.

Everything including the filter is in the tank, not user friendly if you have to replace stuff.

I ammended the copy of the file I use to say (started late 2002), but with the conglomeration of minutia one collects over the years its no better than even money that Ill find the corrected file the next time I go to post it

For me, I'd choose the lower mileage car and then put things on that you want as you can afford them.

Changes for 2003

Wheel Locks are no longer provided

Early production convertibles had one gas strut for the trunklid, later models got 2

Late production 03's got an improved fuel system

DuPont softened the paint formula on all 03's to try to limit rock chips

03 was the 1st C5 to offer a dash color other than black (shale in 1SC cars)

RPO 1SC - a 50th Anniversary Edition was offered (not in Z06 trim), the 1SC option and accounted for 1/3 of 03 production

Spiral Gray - new color

RPO F55 - magnetic suspension was available (std on 1SC) Countless dealers fail to remove the shipping blocks (shock stuffers) on F55 equipped cars, resulting in harsh ride

Factory and Museum News - 50th Celebration, JD Powers award, Museum 10th Anniversary, VIN raffles, Cadillac XLR begins production at BG, A change from Cave City Chevy to the Museum for R8C PDI (Pre-Delivery Inspection), C5R Undefeated 2003 Season

In my opinion I would stick with an 01' or newer. Based on my research it appears that the most adjustments and upgrades were done in 01'. So I would say the lowest mileage 01' or newer you can find. There are some really nice cars in this range out there. I would try to find a car with the fewest owners as possible too. This is not a deal breaker because there are cars available that have been passed along to several owners and they have been treated very well. It seems though that the more hands a car passes through during it's life time the more likely it is to become neglected. I would also recommend a carfax or something comparable as an absolute requirement. It doesn't cost that much and can reveal an ugly past. Just gives a little peace of mind. That's my 2 cents.

Some good points, but also some errors and missed points. For one Z06s and Coupes/Verts never shared the same block.

Also 2001-2002 Z06s, there were more changes than listed such as sodium filled valves.

Suggest buying a Corvette Black Book, lots of useful info in there. No matter what year C5 its still an amazing car.

Don't be shy of the late 03's and 04's due to the cross over leak. Only a small percentage of Vettes experience this, and even still Chevrolet is now covering the repair for 10 years total after original purchase date. So for the next 4 years GM will cover it.

I'd go for the lower stock and mod it to your individual taste

But my understanding is that some, not all, are being covered.

By that I mean some 04's, not all. Don't think any 03's are included unless GM did a 180. There's a long discussion on 'cross-over' topic which has the current status.

Actually, they did. They shared the same block casting. In later years, the only real difference between the Z06 and coupe/vert was the heads and cam.

I looked at options, mileage, condition. Year model was not a issue as all C5's basically look the SAME...
I looked for several months and I finally found the perfect car 400 miles away. I paid a premium for a clean, garage kept, never driven in the rain, adult owned and driven, clean carfax, no accident C5. My car had only seen the dealer twice. Seat Belt and Column Lock. No issues!
My 98 was listed for $22,500 and after 3 weeks of going back and forth, I paid $20k and ended up with a immaculate 17,500 mile 1998 C5 Coupe.
Best of luck in your search! There are a lot of C-5's out there with 1 to 300k miles on them. Just remember, you may save a few bucks by settling for a high mile Vette, but, you could more than make up the difference in repairs. Food for thought

With all the info listed, I'd probably go for at least an '01, because of all the changes implemented that year.

The only advantage I would see in a 01 over my 98 would be the wheels. Mine has the "wagon wheels" that some tend to razz about. Other than that, as for the discontinued items on the 97-2000, it won't be too long before ALL the C5's will suffer the discontinued part Kool-aid.. Anyone own a 2000 or older Caddy STS? My sister has one and is about to trade it in due to NO parts available when it breaks. Do you feel the pain? Its not just GM.. Its all the Companies. Correct me if Im wrong, but I think they are only required to have parts available for 10 years. I once thought it was 7. Oh well...
That was just an example.
