75s are absolute shit. They're claustrophobic, they don't drive all that well, they all seem to smell, manual ones are plain horrible and the auto ones are merely tolerable. V6s make a nice noise but don't seem to actually do much. My 73-year old ex gaffer had six of them at one point and all the current ones (three I think) he's had chipped to 160bhp as he's scared he'll get done for loitering. He loves them, I hate them.
I've had two 406s, both diesels. Pre facelift 2.1DT for me please.
Oddly both have the same issue - the sills rot out about half way along the back doors.
