I am considering the purchase of a 1990 190E 2.6 with 134K miles on it. I would like any information on the expected reliabilty of this vehicle, any weak points, or any other tips. I have over 18 years of automotive mechanics experience (rebuilding engines, transmissions -A/T and manual, setting up axle gears, etc.), but very little on European vehicles. The current owner is well known to me, and he has always had the vehicle dealer-serviced at regular intervals. I do remember the front brake rotors wearing out rather soon. Somebody told me that M-B rotors are *soft* for better braking. I have also heard the A/T can be weak point on this vehicle. Is this true? Also, are service manuals easily obtained? Thanks for any info.
