A car motor should last about 10 year, you can more from it, if you stay on top of all the maintenance and you change the oil every 3,000 to 5,000 miles.

Kiddo82829 Mine is at 160000 and the transmission is gone. I’m trying to decide the same thing. If I get a new trans then will the engine go out next? Maybe you should consider the same thing. If you get new engine the trans might go? It’s a tough decision!! Have you made yours yet?
