Thanks. I've been doing the same searches and have been coming up with pretty much the same info you got. I'm not going to buy a brand new one. I already bought 2 brand new cars in my lifetime and after the first time I said never again. Then two years ago I bought the wife the RX330LegendGS said:Hmm.. Not sure about the V8 vs. V6 reliabilitly issues. Definitetly a toss up, but I guess the key would be whether power is more important to you than gas mileage and vice versa. As for price, I did a quick search and it seems like the 2004 CLK500 is priced around the same as the 2006 CLK350, so this probably doesn't help the decision making process a whole lot.
They did have a CLK55 AMG Coupe in 2004 and 2005. Not sure about 2003.
