86 420 sel

[walt12]

Hello People,

I have just got 86 420 sel and I love the car. I would welcome any tips on what I should do first as far as maintance.
T
he car has 240,000 miles on it. It runs pretty good. But as a newbie to Mercedes I just want to know what I should do first. I have 4 Porsche 944 and the first thing I did when I got them was to change the timing belt. Do I need to do something like that to the Benz?

Also the cars has radio problems I would like to keep the Becker Grand Prix, to avoid the hassle I may just put in an aftermarket unit.

Thanks
