1980 Mercedes-Benz 300D Diesel Non-turbo, daily driver, good paint and interior

1980 Mercedes-Benz 300-Series Description

This car has been my daily driver for a little over a year and I've done several 200+ mile trips on it with no issues. Always starts up well, even on cold mornings. It has 261k original miles and the odometer still works. I recently got a 4x4 and don't have room for 2 cars. It's the 5 cylinder engine so it'll be a bit faster than a 240D but not as fast as the 300D turbo. Never needs to be smogged and fees are paid until August 2019 (photos taken before I got the new sticker). The paint and interior are in great shape for how old it is, there's a bit of cracking starting on the passenger seat but overall it looks great. Here are the issues:
- steering lock will lock up the ignition if the key is taken out. I've been keeping one key in the ignition and locking the doors with the other one
- vacuum leak somewhere so all of the doors have to be locked manually and it shifts too early (so it's even slower than usual)
- small leak on the top of the windshield, water drips into the car
- slow oil leak, don't even have to add any oil between oil changes
- slow transmission fluid leak from the pan, have to top off fluid every 8 months or so
- the usual w123 dash cracks and cracked rubber moldings
- A/C doesn't work
- front doors are missing the "pockets". I got the car like that, no idea what happened to them
