I can also recommend the 190E 2.6
I haven't had any major problems to date.
If the car still has the original alternator, replace the voltage regulator at the back of the alternator. This is cheap at around 35 bucks and will save you from a roadside assistance call.
I have also gone through 2 serpentine belt tensioner shocks in 40 000kms. To be fair, I drive very fast on some less than smooth roads.
Upgrading the front end to the european spec lights with clear blinkers takes years off the car.
Also the back window regulators seem weak on these cars. Mine are still original but, I rarely operate the back windows.
Good luck with yours and take care.
