C350
Engine overrun
Love my C350 sport (28000 miles). It has 95% or more of the available options for a C350 including park assist, distronic cruise, lane departure, blind spot monitoring, 18" AMG's with Michelin A/S 3+ tires 
and more. The only thing I miss that my wife's C300 has is Smartkey, My issue is this during hard acceleration after lifting the throttle the engine overruns and takes some time to upshift to the next gear (up to 3 or 4 seconds). Have had the transmission flashed as it had considerable delay upon initial start up. Also does anyone know if brake rotor out of round would be covered with this low mileage? Haven't figured to thank anyone yet but hopefully I can figure it out.
