So if Mark gives you a completion date next week that will leave five weeks to achieve completion, then to get the car back to Germany carry out additional work, complete all the paperwork and get the car back to the UK ready for JAE and magazine photographers.
Have you worked out how many hours work you have to do on it when it is back in Germany?
Hey if all else fails I'm sure me, spanner man, sore **** and big bones can make a trip over to provide you with the right skill sets :D
