What are some cars that you think are underrated. I personally think the 04-06 Pontiac GTO also known as the Holden Monaro is underrated. The looks weren't the best I agree but I don't think it looked terrible. It was good enough looking. It handled well and was nice to drive. Plus it came with LS engines which are some of the best engines ever made.They're bit of a cult car now, and I'm sad not more people like them. I think that's due to GM using the GTO name on them. I think they'd be better remembered, if GM would have named them differently. Either way the GTO is still a car that nobody really gives a thought to and is a great performer.
