I'd get the Q45 as my grocery getter. My other cars would be a nice BMW M3, a 3rd-gen RX-7 with a 20B engine swap, and maybe an Aston Martin V12 to round out the mix. Oh, just to have a Nissan in my garage, I'd get a Silvia too. n_n
God as my witness, I'D BUILD THE FASTEST G20 ALIVE!!!!
course, if i won the lottery, i could prolly drop an RB26DETT in there...and then another in the former back seats to drive the rear wheels...both with nifty Magnetti-Marelli F1 paddle shifter thingies...and, and, ID ROLL IT ALL ON DUBS.
