I'm new to the forum (and the VW brand in general, too). My DD is an F10 528xi (I do lots of long-distance trips; almost never drive in the town). The Golf R I've on order is planned to be my wife's DD (she only commutes to work within the city), as well as my toy for those spirited driving moments

(the 528xi is no good for it - to large, heavy and with this particular engine, a bit underpowered). I had a tough time deciding between the Golf R and the A 45 AMG; the thing that helped me make up my mind was lack of any suspension stiffness adjustment in the A45. Needed not so much by myself as for my wife so that she doesn't complain on comfort too much.
So do you guys think it was a good choice, even considering the Mercedes has 360 hp vs. "just" 300 in the R? Apart from the chassis, I also got tempted by the many reviews and comparisons claiming the Golf R's better handling and ride. Please tell me I didn't do a stupid thing - price-wise, a moderately loaded A 45 AMG was withing my reach!
