Maginty, I look forward to seeing your new MPS soon.
As to daily drive, I've got an MPS6 so can't comment on the 3, but I do have a stiffer than stock suspension set-up (coilovers that are firm) and the minor jarring I feel on some bad road sections is not too bad. The 6 speed is fine in stop start driving, though Perth has much less traffic than Melbourne, but what I've found is that on a slow crawl there is enough torque in these motors to pull from low RPM in second, so IMO traffic is cool (crank up the stereo and enjoy)
Good luck with it
Chris
