My wife does know how to drive an under powered car. She drives the 240D when I am not. We also have a military troop carrier with only 90 HP that she sometimes drives to Starbucks to freak people out.
Unfortunatly the 220D was not "as advertized" The "impecable cosmetic and mechanical condition" was a rusted out trunk, the pedels were rusted off of the floorbord/firewall, the just installed "brand new engine" wasn't even close to new.etc. etc. etc.
I guess I have to look at the 190D or keep holding out for a W123.
