I'm still waiting for confirmation, but it is highly unlikely that this will happen. It is likely however, that the new direct injection engines, whenever they come out, will have more horses and better fuel economy I seriously doubt the C will get the 3.7 this fall, if ever. I have read that the 3.7 is sort of an interim engine.
24 hours, that's crazy!! MB gives you up to one year from purchase date to get the extended warranty. However, they are strict about enforcing the one year policy. I might get one after a year, see how much I still like the car. I like getting new cars every 2 years (like, doesn't mean it always happens!), so I'll think about it.I bought the 7 year/100,000 warranty from my dealer for $1990. He only gave me 24 hours to think it over. So far I love my Benz, especially the bi-xenon. I can't believe how bright they are. The only thing sucks is I already have a paint chip. A dump truck was dropping little pieces of concrete chips all over the freeway. ARRRRH!!![!]
