Made an off-hand comment about a 300D being a good replacement for my roommate's aging and slowly dying Passat, and he's now fallen in love with the idea and wants to go look at a few. What are the big, potentially catastrophic items I need to look out for?

If the compression tests out, you should be good. There WILL be some sort of mildly irritating vacuum leak that he can either fix (involving a trip down the MB vacuum leak rathole) or just live with it as long as it's fairly slow. I used my vacuum leak to as an indicator for when the engine was warmed up in the morning ... if the vacuum system recharged enough to pop-up the other door locks, the car was ready to drive :D

Seriously though: oil system! The pressure gauge MUST work and he MUST watch it. I lost mine because a cataclysmic sudden pressure drop that I didn't see in time. Always be scanning the gauges on these old cars.

Got you covered. http://oppositelock.jalopnik.com/vehicle-specif…

The 300D is going to have power everything. Those are all controlled by vacuum so if any switches don't work it is possibly a vacuum issue and not the switch.

He'll also need to know how to adjust valves, and it's best that the timing chain's been replaced at least once.
