A sunroof CSi, a rare bird. Looks like a nice one. $39K in 2009 was all the money for any non-CSL coupe, and then some. Quick question for the cognoscenti - there's a B34 3.5 in this car now, and according to my research that gains a whopping 15 horsepower with a Euro B35 - a bit more torque as well. My question is does a 3.5 really make that big a difference in the drivability over a standard (200hp) CSi setup? So much to do a full engine swap? Not meaning to hijack the thread, but seemed a good place to ask. NOTE: In reading the listing further it seems that there's a performance cam (no degree info) and domed pistons, so possibly more than the usual 15 hp increase. Anyways, I still am interested in what would be the most desirable (non Motorsport) engine upgrade over the standard CSi setup.
