Lets get into the nice driveability youll have when spending time behind the wheel ,a tighter more nimble chassis is a well deserved payout when your done.I can say while driving my 300cd around the hillcountry here in Texas ,the 125hp that the 617 turbo delivers is more than enough goat to realize climbs and turns ,I just wish I could of video taped the day for prosperiaty ,that fall day was quite the view .The 300cd is one car that would be the closest to your SLs wheelbase ,106in compared to 96in for the SL.If you added some CLK rims your tuned suspention will just be unreal.
