Which car would you choose?

Personally from the information given I would take the Impala it has less mileage and Chevy is generally pretty good(still its all about preference), but it all really still depends on how well maintained each vehicle is, current oil changes and maintenance, ect. Make sure you check this stuff thoroughly, check the color of the oil if you can, stuff like that. Also ask if there is any receipts or doentation on the car, and also if it is at a dealership ask them to provide a carfax if possible. Good luck with your car hunting!
