I've never seen anyone post exact shop times here, I'll be interested to see if someone does. Most shops charge between $70-$80 and dealers are slightly higher.
If I were going to take a guess, I'd guess they're going to ding you for $4000. Heck, I bet the tranny will cist $1000-$1500.
A 140 chassis Benz can be expensive to maintain.
