That's a difficult question. I hate a lot of cars. Let's see...
- Anything with GM's 2.8L V6. I've had a few cars with that engine... two Chevy Celebrities who's head gaskets went on within a week of my buying them, plus a third that I didn't buy because I realized that the head gaskets were bad ahead of time... and an '85 Cadillac Cimmaron, which was a fantastic car, but had bad bearings (went through two engines in 98,000 miles that way!).
- Neons. Whether it be Dodge or Plymouth, something about Neons rubs me the wrong way.
- The Ford Taurus. Underpowered, even with a V8... I especially dislike the 1990s "bubble" version.
- The '80s era Chevy Nova. I will never understand how you can take a '60s and '70s muscle car and convert it into a four-cylinder rebadge of the Toyota Corolla. Sacrilege!!!
There are plenty others that I don't like... but most cars have some kind of redeeming quality. Mostly, it's the drivers of cars that I don't like.
