Wanted: Looking for Mechanically Sound Used Car

Son just turned 18 so I'm looking to find him a good used car.

Doesn't have to be anything fancy but I'm not looking for a gas guzzler either.

Trying to find something that is mechanically sound and good in the snow.

Make/model/year not as important as the above. If you are selling a used car or know someone who is, please drop me a PM.

Thanx!
