Corvette Magazine regularily does an article on market prices for each generation and special niche Vettes.  I don't recall where they are in the rotation but you could check the stacks at your local library for back issues.

Wow!! You're starting with one of the most popular Shark cars there is! Prices will be quite high, especially for a restored car. Plan on around $40-$50,000 for a quality car, depending on what other options it might have, such as headrests, speed warning, A/C, etc.
A nice, everyday "driver"-quality car will be a little less...$35-$40,000.
Good luck with your search! I hope you find the one that really knocks your socks off!! It's always best to buy the best car you can afford...never "settle" for something less than that.

Welcome to C3VR!!! I see you're a "local"!! Good to have ya!

Welcome to C3VR.

Thanks everyone for the nice welcome!  My wife has been putting me off for years in buying a car and now everything from mid to late 60's vintage is all but out of reach for me.  I sold the car that my wife and I dated in (1965 Mustang Fastback) while I was in college in the early 80's.  The guy I sold it to still has it and it has been sitting in his garage since 1986.  I tried to get him to sell it to me a year ago and he wouldn't even discuss it.  Since I could not get that car back (My wife would have objected to that one) I have since began looking into a '68 or '69 Corvette.  Since my wife has no interest in it, I must convince her that it will be a good investment.  I know it will be much better than investing in a CD and I will have fun with it at the same time.

I'm in Irving......not far from you.   I went with a '69, small block 350ci/350hp.......the work horse engine so I can DRIVE IT and I DO....  Good luck in what car you decide on and if you need any help, let me know.

There are a lot of big blocks 68 & 69's that can be purchased for $20,000 to $25,000.  It just depends if it's been restored or been put together to be judged by NCRS (National Corvette Restoration Society).  Those cars will be $45,000 to $75,000 usually.  If you're looking for the fun of just having one, a 68 or 69 are great choices and being chrome bumper cars they should hold their value.  However if you want to get into judging, the 68 can be hard to find (dated) parts and there were a lot of one off parts.  I have a 68 and know about this.  It can be real tough to find some of the parts.

okay welcome to the site it is my job here to screw everything up, have you considered the 1970 convertible?  brief outline: strike that year low production numbers, lowest number of converts since 1962 (if memory is good) and if you have the capital to use find yourself an LT-1, they only put around 1243 or so of those optioned engines in ALL of the production cars.
So if you want an investment or do you want to enjoy it, I personally LOVE driving mine so will i am interested in the resale value it is never going to keep me from driving it.  just want i am saying is that day when the vette is worth 6 figures will you still drive it?  thinking i will.
welcome
Larry
