Here's my first mod: A label for the on-off switch. 8)
It bothered me a bit that you need a wrench to take off the little cover over the on-off switch, so I went to my nearby Ace Hardware and picked up a couple of appropriately-sized (metric) screws. I wanted thumbscrews but settled for ones with pretty big heads that can be grabbed by fingers.
Then I ordered an official SCCA (Sports Car Club of America) on-off switch label like you are required to have on your racing car, and stuck it on the cover under the luggage compartment.
