If you don't know which of those 3 totally different type of cars you would enjoy driving most, Im not sure what anyone here can tell you that would be worthwhile. Personally I have used a CLK BS as my daily driver for the past few years and have put 25k miles on it. I think its a great daily driver and a lot of fun to drive but then again I enjoy a firmer ride. You may not. I personally do not like large luxury sedans no matter how powerful. You may. The point I am getting at is you don't know mine or anyone elses personal driving preferences on this board nor do we know yours so a question like this about 3 totally different vehicles is kind of pointless. If it was my money I would get the BS and use the extra $40k -$45k to buy a used G500. I currently also own a 2003 G500 since new with 100k miles on the odo. Its a great truck, has enough power for what it is, and still looks as good as the new ones. But thats just me.
