But look at GT and lowly S4 valuations. Same thing. I think 6 months to a year will yield some interesting data. The 928 population is fairly small with about 3,000 cars made per year from 87-on, no US 93 model and very few 94 and 95. Looking at 928s to buy, taking out cars like the Club Sport, I would focus on 89-91 GTs. I hope to get one in February if it is still available. I would also look at the European delivery early cars. All of the hp without all the weight of later cars.

As we all know they are complex cars, some with a typical Porsche major engineering design flaw built in, thrust bearing, cough cough, and electrical gremlins are an issue, but after removing and dismantling my 928 motor, I can say from that experience, it is an easy car to work on. There is a thriving, enthusiastic DIY crowd on Rennlist and I expect it to only grow. Like 911s, they are incredibly rewarding cars to drive and drive fast.

There are 4 different lines on those graphs. What do they represent?
