Looks suspicious on the MOT front being advertised at 50k miles, first MOT @36k in 07, last MOT 84k 2017.
Best case I'd say it's on around 70k miles if it wasn't converted prior to first MOT, if it was then the 84k will be correct.
I'd go have a look, see what condition it's in and how it drives, be very wary of rust to the underbody, especially if its not been looked after with regular undersealing.
I bought mine from ebay seller time5555 up in Newcastle, he has a fresh import in for £9,450, you'd probably be able to chip him down a bit but again be thorough in your inspection and make sure you give everything a good going over.......
