I came across a 1959 Mercedes 190D diesel, 4 speed manual. Its in excellent running condition, though the interior needs a little work. I'm very very tempted to buy it, however I've never owned a car more than few years old and dont know what to expect. As well... I dont have tons of spare cash to pour into it though I should have enough to do some minor upgrades, and I would be making this my primary vehicle.

Anyone have some advice??
