Porsche 928 MAINTENANCE
HISTORY
This is a very
important part of ownership for these cars. They demand
attention and do not take very well to being treated like most
other makes of car would. Don't forget that Porsche last
produced the 928 (GTS) in 1995, and even then they only produced
a handful of these, so they are at least between 12 and 30 years
old now.
I've put together
a history report from my 1981 928 that's been collected over the
years since it's delivery to Australia. It's quite lengthy as
you would expect from a 26 year old supercar, but has some key
maintenance tasks that other 928 owners could benefit from.

An interesting
hand written note I found on this invoice is an add for the sale
of the car. This is 4 years before I came along to buy the car.
It reads;
'For Sale
1982 Porsche 928 auto. Aust. delivery with all 'S' options,
white with dark brown interior. Mechanically sound with full
service history. Bargain prestige driving at $12,950'.
The 'S' options is
true but it's a MY1981 not a MY1982. I wonder who the
lucky owner was then??
