Shall I buy??

I'm crap at parking esp with our big car (Sam will say that ours is not a big car). Ok, it's big for me. Just me!!!

Thinking of whether to buy the parking sensor from Halford. Costing 99 pounds but I will have a better piece of mind.

Let see how I get on with my learning to drive in the car with Sam this weekend... Got a feeling he sure going to shout at me one...
