5: Buick Riviera (1966-1970)
Buick also had its fair share of successes with the muscle car market, and the Riviera is one of those well-known entities. The car had a lot going for it with unique styling and a powerful engine, coupled with the fact that it was luxurious. Sadly the Riviera has been hit especially hard by the current muscle car “bubble” and the prices are outrageous.
You can expect to spend a good chunk of change for one of these in reasonable condition. And that’s including the massive investment you’re going to have to put into repairs and the eventual engine replacement.
