I don't know about my first choice? I'd say 02-04 though. I happen to love the msrc that was only available on 03 and 04.
Don't worry about the 02's.

Is the '02 problematic? No

Are there common problems, Yes... and I have it almost all of them...

- Leaky differential seal - see Junkman2008's DIY
- Fuel gauge erratic readings (because of bad sending units)
- Door Control Modules - see Bakersfield's DIY
- Grounding issues - see BillCurlee's Sticky

This might not sound encouraging, but from an overall standpoint, I believe the car is very reliable, and, although these problems are common, not everyone is guaranteed to encounter them. Even if you do, as noted above, you can find DIY's on them (although I don't know about the replacement of the fuel sending units).

Actually in the 2002 model year there were several changes by GM over the 01. I tried to find the list with a search but did not find it. The changes were not as dramatic as the 07 to 08 change but when I read it I was glad I bought the 02.

All well known problems. Its been fairly reliable for a few years now
Then you have the cracked wheels
and you also have the Steering wheel locking up.

After months of research on this forum, I decided I wanted a low mileage 02. Then after months of searching I found one and bought it.

there should be no difference in the 2001 thru 2004 coupes and verts. All have the same motor, tranny's, ....

if there's one thing the 2001 and 2002 can offer is standard (non-sport) seats, and manual HVAC controls.

Starting 2003, all C5's came with the digital dual zone HVAC control and sport seats.

I intentionally ordered my 2002 without the sport seats because I simply can't get comfortable in them; no matter how much I fiddle with the controls.

As others have said, everything I've heard and read is quite the opposite...''02 and newer are better (fewer quirky problems) than prior model years. Didn't know that when I bought mine, but after a year and a half of problem free fun, I'd say its true.

no two cars are a-like, some have brake issues like the 02 and 03; according to CR the 01 and 04 were least problematic of the C5 models. IMO the 97-00 were the same as were the 01-04. I love my 01 vert with zero problems so far 17,387K.

I had to put a new battery in my 02. The original only lasted 5 1/2 years.

Column Lock ???

I looked at your forum profile, and it is blank. Is your 2003 a manual or automatic ?

Starting 2001, automatic C5's no longer received the mechanism.

Two of my neighboors have C6's and previously owned C5's. So I informed them in my quest for a low mileage 02. One of them had an 02 and it broke down so he claimed that it had like 3 faulty pistons or some crap like that. I asked to see what you guys said because well...there kind of *******s and they never bother to clean their own Vettes. Since I kinda just answered my own question and all, ill say thanks for the feedback

Give me 2 months or so an I'll have 02' black targa with 21,000 miles... and then bring on the MODS!

Glad to say my wheels are fine and I have an A4 so no column lock. I'm sooooo grateful for that fact.

Those problems of course are common to all years not just 02
