I’m in the same boat with a 3 hour one-way drive to my Lotus dealer, and I’m planning my first return trip this coming summer. A few thoughts:
1. Get a good OBD II scanner for some DIY diagnostics and code clearing. Not hard to use one. This Forum has several threads about these scanners.
2. Consult this Forum frequently for advice, to potentially help you resolve any difficulties on your own or if faced with an inexpensive problem, get help from a local mechanic who knows British cars (join a British car club?).
3. Save up your warranty work as much as possible (including software updates) for the inevitable trip to Boston, to coincide with that “night out on the town” (special occasion shopping trip?), during the warranty period. Splurge on a nice hotel while there.
4. Marry a certified Lotus mechanic, or encourage a family member or close friend do so (lol).
5. Purchase then open the first rural Vermont Lotus franchise (lol x 2).
6. Finally, purchase an Emira which will have absolutely no problems and never require any software updates (lol x 3).
Fortunately for me, #6 above applies, with the exception of a couple of recalls and software updates my dealer tells me I need. On a positive note, I know I’ll enjoy the drive and I’ll be able to stay with friends or family, while there. Good luck!
