It's on the road! Actually it was on the road months ago, just in time for the end of summer. I wasn't happy with the performance of the original inverter setup. So I dropped the subframe once more and replaced it with a Outlander inverter to match the motor. I also brought the charger back so I could use the original fuel filler port as a charge port.
Went through the MOT no problems, done probably 500 miles in it so far and it's been pretty good. I've added a little bit of regen that is activated by the brake lights. I still need to change a couple wires over so the speedo actually works. I've just been using the mobile phone and also the rev counter, which in 2nd gear every 1000rpm is about 10mph.
In terms of gears I usually just leave it in 2nd gear, which works just fine at all legal speeds.
