room is a small issue with these cars, not great for tall people. If you have a manual tranny this can be a bigger problem with little leg room trying to push a clutch. the limited seats are a little thicker and trying to lay the seat back without putting my knees into the dash is a close one, but ok. I like to be reclined while driving and the SLK and base model cloth seats have headrest that pull up allowing the seat to go back further to where the headrest support bars can go right up to the gas tank cover/partition. with the headrest a little above the partition this allows the headrest to go back a couple extra inches making it just right for me. I think my base model is now the cat's meow with these seats and with some other cosmetic and functional modifications
