9: 1969 Pontiac GTO $75,000.00
The GTO is another iconic muscle car that needs no introduction. It was originally an accident. John Delorean wanted to sell a powerful sports car under the Pontiac line, but GM wouldn’t let him. So the GTO was sold as an appearance package instead. Whenever Pontiac is brought up, this is the car that comes to mind first (via Work & Money).

What made the GTO so great was the lightweight design and the powerful engine, but that would only get the car so far. Nowadays, the GTO commands an extremely high price tag, and the only reason for this is the brand name. Junkyard models are going to ridiculous amounts and it appears to be stopping.
