Just bought a 164 after admiring them from afar, now I am admiring from underneath ! Bought this one with a faulty auto transmission ( ZF4 HP18 ), thought it might be the valves but...always a BUTT.....It drives and changes up Ok for the first 2 miles then it slips and there is no drive. Turn it off and let it sit for 3 - 4 mins start her up and she goes OK for another 2 miles then slips again. It keeps going like this 2 miles 3 minutes off 2 miles. I thought what the heck I would strip it down anyway...but came across a receipt in the bundle of receipts that claimed the "2nd Clutch" was faulty..then WHY would it run then stop ??? On taking out the filter, that looked like it had never been taken out before, it was spotted with metal fillings..so something is very wrong. Already bought the overhaul kit..so we will see..in the meantime - Guesses ?
