the BMW. Even though Mercedes are my dream car the C Classes are just lame. My old man has a CLS 550 i love that. CL Classes and S Classes are the 2 nicest Benz's.
Both are very nice, sporty cars. The BMW appeals more to a younger audience. Older, 55 and-up drivers seem to be more inclined towards Mercedes. I'm only 47, so I would lean towards BMW.
2006 is a great year, but so is 2007 and they are now coming down in price. Check the article. The deals they have on eBay make it very tempting for me. Lucky you.
