i have a 1979 corvette, 79000 miles, does not run, body is straight and oxidised. what is this worth?

Very hard to say without photos. 2 to 5k depending on a lot of things like options and condition.

It could be a parts car or it could just need a tuneup.

good body- if it is a good interior and it is all original and all there it could be worth somethin' ......5 years ago these were bargains- nobody wanted an old 200 hp automatic Vette- but now the style is being recognized- and they have at least doubled in price- even not running, $5000- and if you keep it it will be worth more next year-

No photos, hard to say, but if it is straight, and interior in fair shape, I would say around $4500, to $5000, cause if engine wont start , it could be a can of worms, then get into some heavy expense.

How long has it set with the old gas in it? Clean out the fuel system, tank and all and put in new top obtain gas. Change the plugs and wires, if it is a carburetor, have it reworked, if it is an FI", clean the jets/injectors and all lines. Make sure you have spark to the plugs, and it is in tune. A new coil is not expensive to replace either. It should start. $200 to $300 for a garage to do the work. Half or less if you can do it. Good luck. Enjoy the ride.
