Euroclassics on Midlothian Turnpike used to be a Lotus dealer until couple years ago, they still do service work, kept the special tools, diagnostic instruments, etc. Young guy works there is very knowledgeable (Carmelo), I've found them to be reasonable, do quality work, don't try to sell services I don't need/want. Not sure how they are equipped to service Evora's, but worth a call. Otherwise, like you said, it's Bethesda MD or Winston-Salem NC.
There's a cars-and-coffee in Richmond every other Saturday, search for the group on Facebook, bunch of interesting cars and nice people usually turn up.
