I've been looking at a 08' malibu that is for sale for $12,000. It has around 36k miles, is a LT with the ecotec. what all should I look for when driving it?? any tips?? I know it was a rental but other than that it seems fine, they only offer 3 months of warranty, I did a test drive annd it drives fine, the only thing is that it feels heavy for that 4 cyl but I red thats normal; it is not a chevrolet certified, that is my main concern about it but I figure that it should be okay with the mileage it has, what do you guys think??? Any help would be appreciate it
