They both have 4 doors and 4 wheels but that's about it. I think the new impala and monte carlo are both real ugly!!! I love the 59 impala, the 63 and 64, oh and the 90's one. But the new one is a joke! Just using name recognition to sell crap that is aimed at a market who will by something with no soul.... Sorry, but I'm really upset with chevy for destroying a good name. It's like what dodge did with the daytona. Nothing on it was like the 60's muscle cars... Ford is finally reviving the spirit of the thunderbird... good for them!
