did 15 hour sraight in mine. Trenton, Ontario to Truro Nova Scotia.
I tell ya. I was tired and babbling about noodles afterwords, but I wasnt sore. Best advice I can give you is to stop when youre tired. Dont let the black dog bite you.
Aside from that. If your flyin solo, a cooler fits nicely in the passengers front footwell. Saves you a bit of coin if you hit a grocery store for snacks instead of gas stations. For the micra itself. Change out the oil before you go, and it will be fine.
