I use your website a lot as a reliable source of background information on new cars. I am thinking of changing from my current Porsche 996 Carrera to something with a little more luxury and refinement - a Mercedes SL. My budget is about £25-28k. I notice that you only give 3 stars to the earlier models and 5 stars from 2006. I would really like a 500, but the newer model is unlikely to be cheap enough soon. Am I better going for an older 500 or waiting a few months until the newer 350 is in my budget? Also, would you stick to Mercedes with its cast iron warranty or look at cheaper independent dealers?
