I think you may well find I did plenty of all of those! Many a trip to Anglesea for trackdays, and of course going to Wales always involves rain (but the roof only leaked if you put it on from the driver side, do it from the pax side first and it was fine!), and I did discover that the wiring for the front lights was done in two different colours when trying to add HIDs. Typical Lotus!
Loved it though, from sitting in those gorgeous bucket seats to after I had it mapped and there was no such thing as an overtaking space too small. Amazing car.
