I think to trade my SLK 200K with a SL350. But I'm not really sure about this. I found a second hand(6k km)SL350 with a good price. It's black. But I also think to buy a new Porsche Carrera 4S at the end of 2006's summer. If I got a SL now, I don't think that I can buy a Porsche next year. What do you think about this? Thanks!
