How many miles till i rebuild a 2008 saturn outlook

Hello, I can say that any 14 year old 170,000 mile vehicle is at risk for needing major repairs in any of the various systems of the vehicle. It's a very high risk situation even in the "best" condition, but certainly, you could also be fortunate also and not have issues for some time. If I was even remotely considering a vehicle of this vintage, I would wish to see all of the repair records for the vehicle over its life to see how its been maintained. Even then, I'd put money aside to hold for needed repairs that are inevitable in time. Good luck.
