Options, condition and originality are key. There is no way we could give you a fair evaluation here.
40k up
To be fair to all you need to get the car appraised.
If the car is in great shape and all numbers matching then yes it is as the judge is the king of the GTO's.
Very
that all depends on the condition of the car and if it's numbers matching, you can look on manheimgold.com for the prices.
It means that the car still has the original drive train...(engine, trans, etc) plus all other factory original parts. This will make the car worth a small fortune.
Varies greatly, a mint, numbers matching 455HO 4 speed car could bring over $35-40K. A much more common 400 car about 2-20K depending on condition.
The successful Pontiac GTO cars are: Hard top: 65, 176 produced, convertible 9,517 produced, sports coupe 7,029 produced in 1976. There are no model numbers available for these vehicles.
There were 2,170 convertible GTOs in 1970.
1965 Pontiac GTO Convertible (Cabriolet)
Options will change the base figures but Hardtop was 3,753 and convertible weighed in at 3,802.
The base hardtop went for $2,935. A convertible was a couple hundred more.
Well of course it depends on the car's condition and the rarity and desirability of its options. Top of the current (weak) market is probably represented by the triple black 1969 Pontiac GTO Judge Convertible which brought $220,000 at St. Charles Muscle Car Auction last month, September 2010.
