As for importing one yourself, I'm not sure whether anyone will compliance them anymore, as the rules changed in May this year, & I doubt any workshops would be bothering to compliance such a low volume import. The cars in these photos have been sitting in the yards for over 6 months now, so obviously they're not very popular. They're not exactly cheap when compared to Skylines etc. of similar age which can be bought for similar prices, even if Skylines cost 3 times more to insure.
I was gonna get one of these Levins till I found that GT4s were cheaper, quicker & easier to get parts for.
