The marker has never missed a beat mate. I will say they need TLC all the way, no throwing this bad boy in your kit bag for a month before you decide to use it again. Its more of an F1 car than a Porche. I'm looking for £400 excluding P+P and fees.Could be mate but ive heard the 11 isnt as good as the 10th have you had any problems with it at all and it all depends if you give me a good deal im taking a bit of a chance what price you have in mind
