Now boys, you'd better behave and get along, or I'll ground the both or you.....I bought my SRT because of its limited production, the engine was a bonus...at my age...I am tired of shifting....every car I had until this srt was a stick, loved them, drive w/ the best of ya, but I like what I bought...but it is redundant to make some things go faster when there are other ways to get there...it's your money...I had a big block camaro in '71...4 big blocks later, I put in a small block...obtained even greater times....its about the car...we all own XF's so lets try to get along...Now I have been called a **** several hundred times over the yrs and it doesn't both me...a **** I am....of coarse I am a cop.....go figure...
