I think that's why many of us are here, i've had a fair bit of advice and gained a lot of knowledge on here, as well as finding out a lot myself through research.
Hoping to nurse mine through for a few more decades yet, it was a demonstrator originally then a one owner car until his demise when i bought it and became the second owner. I suspect in his final few years, the previous owner wasn't quite as fastidious as he originally was but overall, mine appears to have been fairly well taken care of.
They all need TLC sooner or later though, those with errrrrrrrrr..................... "less cosseted" cars will no doubt find those tasks of TLC sooner than the rest of us and hopefully we can learn from them.
