might also wanna change out ur fluids oil, trans, etc my 300 had been sittin for a long time before i bought it and thats one of the first things a i got done on it
hmmm tough choice there then again i have never seen a tricked out benz from that year ha so that would be kool to do, just do w/e fits ur budget and priorties. Ur lucky that u dont have any rust man, id suggest you do paint if u got the cash frist since the car seems pretty soild or audio system (which is always a must)
