Couldn't agree more with Lee. This message came right to the point. The CLK55 is probably the fastest of the bunch. While it doesn't feel as solid as an Eclass it is also lighter on its feet. Hurry up and put a deposit down on a CLK55 they should be here in either Mar2000 or Dec 2000.
BTW the 5.5 motor is a totally different beast than the 4.3. It is not a stroked out 4.3 motor. The block is different.

Good luck!
