1984-89 Porsche 911 Carrera
Stout likes these models partly because they're cheap enough on today's collectors' market for novice Porsche enthusiasts to buy them.
"These Porsches were made in large numbers, so good ones can still be found for $20,000 to 30,000," he says.
The expert says the models are also "beautifully made cars, with strong though not perfect mechanicals and long-life parts throughout. Rust was no longer the issue it had been in the early 1970s, and the cars were fast and gained a strong reputation for reliability."
