That’ll be the day when I spend $5k on a vehicle that’s not worth much more than that. As hard as it is, sometimes you just have to say goodbye to car that’s become a money hose.One more thing, since you are driving a old car a head gasket or trans can go at any time. Doesn't matter if it is a MB, Toyota, Porsche.
That is why you should always have 5K set aside to deal with such situations when they arise. If that is not within your budget, European cars are the worst choice for people on tight/zero budgets. I've been in and around MB for over 40 years, but I don't get persuaded by the 3 pointed swastika.
If you think your car will be "fixed" after the blower, don't. Other stuff will break, guaranteed. Just sayin'. And on the newer MBs, it is much much worse. The electronics basically brick the car. I pity the fool who is going to try keep a modern day glass cockpit MB out of warranty and out of pocket for the long haul.
Current day European cars are only a viable idea if you're going to lease them for a few years, but no longer than the factory bumper to bumper warranty.
