340R in metro Seattle
There are at least 9 in the US.
Lotus Cars US imported 8 (complete with x of 8 engraved plaques between the seats). Two of them ended up here in the Seattle area and were sold by Park Place, Ltd. (Although, I think the owner's family bought both of them). Those 8 are NOT street legal (although they do seem to see the streets wearing dealer plates once in a while)
At least one additional 340R, owned by a european national and brought into the US as his personal car when he moved here was resold through Park Place last summer. Apparently, it is street legal through a grandfather clause in the foreign national car import laws.
So, out of the 9 340Rs I know of in the US, one third of them are in the Eastside metro Seattle area...
