I'm looking for a new used car and found this one and it seems pretty good. there is some rust but its 8 years old so that is expected. the interior is clean and the engine is really quiet. it seems like a great buy but are there too many miles on it. i'm looking for a car to last me atleast 3 years with probably 10-12 thousand miles a year. any opinions? are impalas good cars? do the engines have a lot of problems with high mileage?
