the front seats on my w123 have gone south and need replacing.

however, the old girl rolls around quite a bit on corners and sometimes i have to hold on to anything handy to stop myself falling horizontal!

as a result i would like to put in some seats that are more supportive, which probably means sportier, and preferably leather too.

does anyone know if i would be able to straight swap some seats from a more modern merc, or is there a contempory model that i might be able to rob some from, (not literally of course!)

thanks in advance. jb
