Well there is not much that can hurt these cars, but my brother did burn out the clutch at about 145.000 miles,needed changing anyway.
The only thing that I don't like on this car is the interior (plastic) it is very cheap and nasty,breaks easy.
Oh 1 other thing the breather pipes get clogged up with nasty oil and water (condensation) but is an easy fix.
Well I could go on about this car all week,i would say it is one of the best cars ever built,its very very strong very reliable, it can take a hell of a beating unlike other cars e. g fords, it has never let us down, I would say it is the best work horse no matter what,this type of car if looked after will live on for ever, I am restoring mine now after 7 years of nothing, but normal servicing,this car is unbelievably strong, I don't see why it will not do 300.000 miles with no problem, my car has been over to Ireland 4 times from Scotland to Manchester about 7 times,it has done endless journeys round town (over 200.000 miles on the clock Say's a bit doesn't it) i no for a fact that this car will not stop.
P.s my car just hit 22,687 miles and still in going strong.
Yes it doesn't surprise me as I no that these cars will do 600,000 and then still fight to stay alive.
