I once had a series 3 1.5SC that had the line 'previously registered/used abroad' on the V5 and it was registered in the UK about a year old. What was odd about it was it was r/h drive, and I think always had been, but the boot release was on the left side of the car - not very convenient unless you had an attractive passenger and needed to lean over and release the boot.
Just out of curiousity that seem a lot of work unless your planning on staying there long term and r/hand drives are a lot more rare than l/hand ones . Why a sud ? Probably cheaper to buy a l/ hand drive 145/147!!
