Matt as I explained it to you at the weekend is there something you didnt quite understand, its really simple...
Firstly buy the car...
secondly, get it pre MOTd although I can tell you now all you need is a horn and fully working lights, which itll prob have already...
Then when you have a MOT, call the Renault Customer service line, and give them the VIN number... They send you a letter through the post confirming year of manufacture etc...
Take that along to the DVLA with the MOT get it registered... JOB DONE
