Hi Dean,

It's impossible to answer that one, I'm afraid, as cars can theoretically last forever if you are willing to spend money on their repair and maintenance. Saying all that, the first-generation Insignia, especially when powered by the 2.0 CDTi diesel engine, is not a particularly reliable car. We'd be slow to invest in one unless it has an immaculate service history and everything appears to be well. Even then there are better used cars on the market for the same price that will give less trouble.
