Parts are dirt cheap and they are easy to work on too.
Porsche parts weren't over the top when I first bought my 968 eight years ago. They've crept up over the last few years and there's certain parts which have gone up four or five times in price
Not sure if this is because VW have taken over, or Porsche don't want people owning old ones anymore
Wonder if the 924 has been immune to this?
Anyway, from everything I've read, the 924 is a brilliant, under-rated sportscar. I've seen several on trackdays and the owners always seem to be having alot of fun. Not very powerful but they have a purity which the later 944s and 968s slightly lack.
