Oh aye, make no mistake - the mk1 is a complex hand built car. There are few good ones left now, and they require extreme dedication to maintenance, and a not inconsiderale bank account, to keep them sweet.
In that sense theyre enthusiasts motors that need constant fettling and cherishing - as they are they are now I wouldn't recommend one as a daily.
There are few really good ones left - I only know of one other as smart as mine, a guy in the VOC who lives not far from me as it happens - and the rest are a world of potential pain that would drain your bank account in short order while you spend months scouring the world for parts.
In terms of cost and effort its like maintaining a DB7 or similar, not for the faint hearted or those prone to cut corners with maintenance. They will bite, you will cry, but you either roll with it and pay the bills or the car will soon be on
ebay as spares or repair.
Im lucky. Thanks to my Dad im a decent amateur spanner man, and being retired I have the time and spare cash to devote to it. Im double lucky as the nearest garage is only 400 metres away and the workshop supervisor is an ex Volvo master tech from the P80 era so anything I cant handle he sorts or advises upon.
