A local fellow has a '65 Chevelle SS convertible for sale that caught my attention.

It is a better than average "driver" that needs virtually nothing. An original SS with white exterior, white top, blue interior, original buckets, console, original correctly dated 283, and powerglide. It had a body on "restoration" about five years ago, including the underside. It didn't need much metal replacement, other than a few patch panels. The trunk and floors are original and seem solid.

What might this car be worth? By the time one paid tax on it, it would cost about $30,000 Canadian, or about $25,000 US. Is that too much?

I dont know about up there, however a couple of months ago, I could have purchased the same deal you have there except in ohio, with the car I was interested in needing a few grand of restoration roughly 7k (based upon personal experience, and me doing free labor) for 8500 dollars. Good luck JN
car was all original, including faded paint with POP

Sounds a little high. If it's in great shape ( not show car) I'd say more like $20,000 US.

You are probably right that the price is a little high. Now, if it was in the same condition but had an original 327 and 4 speed . . . (Powerglides seem to lack appeal.)
