The first 928 (silver 89 S4) I bought was a 1 owner car with 23K miles and totally original and non bastardized . I have religiously maintained it and it has performed without a hitch for 16 years and now has 98K miles. I just found a red 91 928 GT with 24K miles and again 2 owner car not bastardized, and I'm doing deferred maintenance to start the "love affair" over again.
My 89 is now relunctantly for sale as having 2 does not make sense

The 89 is very original with most all maintenance done and kept up. It will be a great car for the next person.
Finding 1-2 owner cars is important since if they could afford it new they usually kept it up on maintenance.
