30: Mazda RX-7
The current automotive bubble just won’t last. The RX-7 is an inflated car that has ballooned in value. The RX-8 is an absolute beast on the race track, but that doesn’t mean that it warrants such a high price tag. The rotary engine is a definite plus but parts and repairs can be quite costly. This doesn’t mean that you should avoid the RX-7 all together.

But there are similar cars in this space that go for a lot less and offer a lot of the same performance. The RX-7 might just be on a pedestal right now, but the price bubble won’t last for a long time. The car is an easily accessible classic that you can find on the open market, yet the high price makes this one a sports car you should avoid.
