I have an 06 Malibu Maxx LT it has ~160,000 miles. When it warms, the transmission sucks and the cooling system is a mess (I recently replaced the thermostat, and did a full flush, and had the fluid and filter done in the transmission).

A friend is offering me her AWD โ€˜03 Subaru Legacy Sedan with 120,000 miles for $1500. Her family has maintained it at dealerships since new.

I usually believe that for every $1,000 you spend on a car (initial investment) you should get 10,000 miles out of it. I spent $4,500 on the Malibu in February of โ€˜16 and have added ~30,000 miles.

Should I sell the Malibu to my mechanic and buy the Subaru, or drive the Malibu into the grave?

If it helps, I live near some superb driving roads.
