Provided I had insurance I would go for it. Whats to stop you ? It`s not as if the car is suddenly going to be registered to someone else or its going to turn into anything else. Its your car , its insured , its got a number plate , its legal ( iva wise ) and it will be taxed. So what if it takes a couple of weeks for the details to get on the dvla computer - especially if the sun is out !!!
