Mine is in surprisingly good condition, given it spent 3 years sat outside in Longbridge after they put 84,000 miles on it and broke the gearbox! In my limited sample of 1 car, now with 100k miles on it, the exhaust system seems to be pretty robust.

I do however have a pair of saloon back boxes in my loft that have been dry stored since 2006 when i bought the car if anyone needs them.
