Two days into owning it and the little blue JDM Copen I bought is still surprising me with how well it performs. I've taken a look through the paperwork and under the bonnet and there was no real clue. Other than a full service, brand new turbo, battery and lambda sensor 90 miles (and £1,500!) ago, everything looks fairly original. I checked this morning and the rev limiter is definitely set to 9,500 and a poke around behind the glovebox reveals a Daihatsu ECU with a big blue and yellow HALF WAY sticker on it. I'm guessing that might explain it?
