If everything works that sounds pretty fair in today's market. I'd bargain lower and go from there. They're relatively rare cars and when good ones come along they're often pricey. These cars go forever, a good number of forum members have 90-93 300D's that have over 400k on them.

These cars are more computer controlled than you might think. The wastegate on the turbo is controlled by the computer. The computer looks at things like the airflow meter and other sensors to control the EGR and idle speed. If any of these sensors is not working or disconnected, the computer will store a code and open the wastegate, resulting in no boost and a slow car. If you test drive it and it's slow (around 18 second 0-60 times), there might be a code stored. I would have the seller diagnose and fix the problem before buying, because sometimes tracking these problems down can be time consuming and difficult. It's also a good idea to check it over for the common 124 problems like the evaporator and such. Do a search and you'll find lots of info.

Other than those little computer quirks, it's a great car. Easily returns 32+mpg on the highway while providing decent power. You get the quieter, smoother, and more economical 602 engine, and all the features, comforts, and great suspension and handling that come with the 124.

The 93 will have had the w124 mid-life face lift with the slight styling upgrades, interior modifications, and a better sounding audio system.

Overall, I would definitely recommend it. They aren't all that much more difficult to work on than the 123 with the 61x motors, and don't require valve adjustments. No 603 head cracking or rod bending problems to deal with either.
