believe it or not the EVO is probably the safest in PK as it'll probably save you allot fo trouble as it has 4wd which can handle our slippery roads, but in a frontal crash the CLK and 350Z will perform pretty well.
i'm sure a net search will yield the crash safety ratings (something tells me the 350Z would probably be higher rated than the CLK).
BTW there is a supercharger that is made for the M112 mercedes engine which can take the power output to around 350hp. allot of peopel with chrysler crossfires have already done it and it is a simple bolt-on kit.
it can get you into allot of trouble with the mods if done in the pro forums:)
however, i should point out that i've been begging the admin to reset my post count for months now. i want to start at 0 again but HB will not allow me.
