I have a 2007 Mustang
, so I have done a bit of research on the history of the car.
If you are looking for a cheap used car, Japaneseis one. Buy something from Japan instead, because old Japanese cars actually work. With this Mustang, you would probably pay more in repairs than you would for the actual car.
You could probably buy an 80's or early 90's camaro or mustang for around the same price if you really want an American muscle car, but you will probably not get the one with the best engine.
If you want to buy it as a collectors car, it seems that you are not in a position to start collecting cars. Get to know them much better first; otherwise, you will lose money and end up with a car that you cannot sell taking up space in your driveway.
