Stowe is beautiful... not real Vermont, kind of like an imaginary town designed to be the "quintessential new england" town.
Burlington (not far) is great too, I go to school there. Lots of fun nightlife and hikes/scenic stuff to do during the day.
The car show is chock-full of beautiful cars (a decent amount of Rovers last year, but lots of really high-end Astons, Bentleys ect) and they go all-out for the British theme, lots of shit to buy; books, parts, ect,
It was $55 to register a car so they're not f*ing around.
I'd recommend it, especially if you spend saturday or friday night in Burlington
