Any car will last indefinitely if you keep repairing or replacing parts. What you're really interested in is the rate at which it goes wrong (the reliability) and the cost of repairing when it does. When the cost of repair exceeds the value of the car, you (should) give up, though it might make sense to give up before then if the reliability gives you cause for concern.How long will it last in the long term? Does that come under reliability?
