It seems that they were cheap looking back now but who would have paid that much for those cars back then? I bet they didn't seem like bargains at the time. $45,000 was a lot of money, even for a Bat.
What are today's bargains?
'73 ~ '77 Porsche 911? Victim of a, albeit justified, bad reputation for severely overheated engines. The Pininfarina styled Peugeot 406 coupe?
Others???
For myself I would choose cars that are pre computer management; cars that the average guy with average tools can tinker with. Has to be a looker. Preferably coupe or two door.
