that bothers me as well.. i have a 1993 ce right now, but the tensioner is broken and i can't really work on it.. might give it to a friend who works on benzes for super cheap, or it has to go to the junker
i had a 95 w202 c280 before with the same engine, it was a pain to work on just like the coupe..
then i got a 87 300e, with the m103 man was that easy compared to these so so easy..
the 400e does intimidate me, and its true i can't afford the gas on it, but its the same as my coupe so bleh..

but yeah there is NO space
honestly i've been looking for a 94/95 coupe for forever but i can't find one within budget :/
