I've arranged to hire a 3 wheeler from the factory for a day in September and Mrs. Bloggins has just raised an interesting point. Does the 3 wheeler come with a cigarette lighter/accessory socket? I am absolutely reliant on my portable sat/nav when I'm driving in the UK and have no idea how long its battery would last if I can't plug it in. Same thing applies for the week in the 4/4 I've arranged with BerryBrook, now that I think of it.
