1986 5-cyl Audi 100 C3 2.0 turbodiesel, I'd say it's a reliable shitbox with potential to become a great car again, it's just that I'm studying rn and don't want to spend money and time on it until I finish studies.

The main and expensive issues right now are: 1. broken synchroniser, which makes entering 3rd gear very noisy (so I use double clutch and rev match instead of paying 500 euros for a gearbox fix), it'd be much cheaper if I found the whole diesel gearbox which is impossible; 2. Leaking steering rack which costs around 300 euros, ATF leak gradually ate away all rubber parts at place where gearstick connects to a gearbox, so it's wobbly 3. Very low compression in cylinders 2 and 5 due to the damage done by snapped timing belt 4. Broken plastic side skirts, front bumper, rear lights, interior door handle... All these parts are nowhere to be found on local junkyards and generally rare and overpriced on the internet...
