Recently bought a 1984 230CE
 

Last week I picked up a really nice Euro model '84 230CE. This is the first gas powered MB I've ever owned and I was wondering what I should be paying particular attention in regards to the engine. It has the M102 and a 4 speed manual. Even though the car has over 162K miles on it, it really runs good, the oil pressure is in the 2 bar range at idle fully warmed up and idles silky smooth. It was owned and maintained by a MB mechanic before the previous owner and the previous owner continued having the same garage maintain it. It's had an excellent maintenance record and the top end along with the timing chain were replaced not too long ago.
I'm looking for some advice before anything needs attention.
