How long can our cars last?

[StuartW]

I/we have only seen one premature failure, a 4.7 GTS that crudded up and oil starved itself. IMHO the V8 is a hardly lump, well engineered and daily driven at low stress so it should be good for well over 200k miles. I feel the rust/body/subframes will be the killer of these cars, not the engines.

Rust has spelt the end of many a car for years and I agree, I don't see these being any different.
You only have to look at any of the car restoration programmes on TV to see that it is always corrosion that is the biggest barrier to getting the cars back on the road. The mechanicals are generally a relatively simple fix compared to what lies beneath
