They usually last forever if you replace the engine and replace parts!It will be bad on Gas Milage though......
No way of knowing without a service record and even then it would be a guess.
6 years
2 years till it rusts out
They should last 100,000 miles.
Chevy Impalas can last a long time if it is well maintained. It should last for 180,000 miles. The number of years will depend on how much its driven.
3 to 6 years
10k or less
since 2006
They are projected to last 100,000 miles. I do not know the replacement cost.
A lot of milage.
With proper care and maintenance, as long as you want it to.
