I have noticed over the last many odd years that all cars go through a period when no one wants them. They sit on the lot and the used guys can't give them away. They were slow sellers when new and lost half their value the day they rolled off the lot. When they are about 20 years old they sell for a fraction of their value.

Then, 15 years later, they are 'Collector Items'.

A good example is the Plymouth Superbird. I remember looking at one in 1969 with a price tag of $7,500. You could buy a Hemi Roadrunner then for $3,800. As they aged no one wanted them since they got poor mileage, the clutch would crack your left knee when you used it and A/C was not available. Now they bring about $100,000.

So what is out there today that would fit this formula? Low initial sales, one or two real drawbacks to ownership when new and a number of drawbacks now that are keeping values low.

Perhaps a SAAB 900 Convertible? A Porsche 944 Turbo? A mid 80's Mercedes 560 S? A Datsun 240 Z?

Would a Maybach be a car like this in 20 years?
