Yes but ignoring the fact the steering wheel will be on the wrong side, there'll be issues will the radio/entertainment systems etc being incompatible, insurance being more difficult to obtain, the hassle of getting it imported and made compliant for UK roads etc.
I've long thought the S550 would look great in British racing green; the GT350 version even more so. Add gunmetal wheels and the LeMans over-the-top stripes in white? Smokin'.
