Since I've still not sorted the IAC issues, it takes a good few cranks to get started, and with A/C on it cycles between idling at 500-ish RPM and 9-1000 RPM if I don't compensate it with throttle. Because I moved one of the A/C relays that usually belongs under the bonnet when I did the rewiring, there is also a loud click each time the compressor cycles on and off.
The XIDAs are good and compliant but are set up at the moment to be a bit underdamped, so can very occasionally get a bit of a bounce going if you hit a series of bumps at near enough the right frequency.
I hate the catch can venting to atmosphere. The smell pretty much gets sucked straight into the cabin when sitting at lights or in traffic.
The transformation from white to black with a red stripe attracts too much attention, is awfully hot in the sun, and I look at all my mistakes where I can see bits of white, stretches in the vinyl or changes in the grain each and every time I get in the car

If I had the time and patience (which I currently don't), I would rip it all off and do it again.
