All the photos I took of my 928 while under my stewardship:

This car had about 18k miles when I bought it. Sold 1 year later with about 22k on the clock.
When you do the belt service you might want to refurbish the tensioner mechanism. If you haven't discovered it already, the 928 forum on Rennlist is quite active and there are lots of DIY guys who are ready to help you get this car sorted out. They also have a bunch of clever fixes like there is a Ford or GM engine mount that fits which is recommended instead of the OE Porsche ones (which are known to fail).
