New to the forum, yes, I've been a guest in the past, finally joined. Bought a 2006 SLK 350 2 years ago. had 34,000 miles, miny condition and all Mercedes service records. Since put another 5K on. Love the car! Alabaster body / Grey interior. Been having trouble with the on/off CEL (checked diagnostic, gas cap related). Ordered a new gas cap today (got the correct part # from a member), hopefully that's all it will take.
