Welcome to the board.

I have an 85 TD wagon, somewhat less than mint, but a nice work car. I think you paid a good price for a running car, and the stick is a big bonus in many ways, I would consider paying $500 extra just for that. I have found I have to spend a lot of time reconnecing/tightening nuts and wires, but not much need for expensive parts. Timing belts and the many cooling hoses must be kept up to date, while the radiator and oil cooler become suspect with age.
Most of the special tools for working on the diesel engine are also used on the VW/AUDI diesels, and the valve shims/tools interchange with gas VW as well. Look at Ebay as a possible source. I am sure LA has some VW diesel experts who cold help you out.
I have a dent, headliner sag, brittle plastics, cracked dash, ground connector degradation, and the passenger door comes unsealed(noise) at 70 MPH, but no regrets. Can't knock the Toyota Corrola economy in a safe comfy good driving car! It siuts my needs well, and runs on recycled vegetable oil which helps with smell and carbon buildup.
Enjoy
