2000 ford focus or 2003 grand am?

I seen these two cars and like them both. There both being sold by private parties. Focus has 155,000 miles and Grand am has 170,000. Which one would be best to invest about 1,500?

Focus. At that age, mileage is king and the Grand Am is not appreciably more reliable than the focus. I would only put what is needed for maintenance in the car.

"Invest" is a pretty strong word. I'd suggest buy either one for a grand and keep the extra cash for repairs.

2003 grand am?
