Similar feeling here. I have an 02 MCS that has been pretty heavily modified for occasional track use and daily driving in the nice weather. I use my Paceman over the winter and in the rain at other times. Even though there is a vast difference in how those two cars handle and feel, the Paceman is just what I need for foul weather driving. It feels very stable, the ride is smooth, and while nowhere near as nimble as an R53, it handles very capably.
I now have just over 15,000 miles on it, and the only issue I have is one of my own making. I installed a rear sway bar from Way Motor Works, and the sucker squeaks really badly, even after greasing. I may have to change out the bushings. Other than that, no rattles or mechanical issues.
