X2 with PH, and agree it is way overpriced.
That is not a 25K car, probably 125K. The older cars do not have the extra odometer digit like newer model cars to tell you that it has already clocked over 100,000 miles. I see many ads that claim this of their car when the mileage is much higher. It is also very easy to buy another speedo off Ebay with lesser miles, have a shop clock the numbers for you, or even hook up an electric drill to the end of the speedo cable at the trans and spin it in reverse to back down the miles - don't think this isn't done.
Look at all the gauges put into the dash. Gas gauge inserted in the left dash pod, 3 gauges where the radio goes, aftermarket tach in the right pod, no headlight push-pull switch on the lower left (open hole), small light (?) above the left turn signal, and.........what appears to be an incorrect 140 MPH speedometer. Looks like the remains of a Grant steering wheel and it may not have originally had the 4-speed as most had the center console and the is definitely and aftermarket shifter boot and shift knob.
A fair price, after I received my PHS documents to verify how much of the car is still original and how much of it has been changed, might be 6-8K and hope for the best, but I would be all over it looking for rust & repair work and expect to pump money into it. My guess is that the engine is not original either and may or may not be a 400CI as all Pontiac engines have the same physical size. Could be a 350CI if you did not verify that it was not.
Keep in mind, there are many "middle men" who promote the sales of other people's cars found on the internet, Craig's List, AutoTrader, Hemmings, and all the other magazines that sell cars. They list a car as if it is theirs and part of their inventory when in fact they don't own it. They can very easily be scammers who answer your questions and send you more photos because they are getting the info from the original source from where it is being sold from. You put a deposit on it and guess what? I purchased a '73 Plymouth Fury Grand Coup last November - I OWN THIS CAR. It is posted by one of these rip off "dealers" in Cadillac, MI for $5,895. https://classics.autotrader.com/clas...ge=2&year=1964
I paid $3,500 for it and you would think it was on his lot when he lives no where near North Carolina. Most of this idiots cars are from other ads hoping to turn a profit by hooking you up with the original seller in a "no refund/buyer beware" you own it deal. MY ADVICE??? If you cannot see the car in person and talk to its rightful owner in person, pass on the deal.
