For my 205 I did this trip....
Picked up the van from Birmingham 5.00pm, drove to Chesterfield J29 M1 to Tims to get his trailer.
Drove to 20 mins past Dartford tunnel crossing after being stuck in traffic as the M20 was closed- got to the guys place at 11.45.
Drove back through London as the M25 was closed or somet...
Got home 4.45am. so about 12 hours.
The next day I got up fairly early and took the Car up to NMS - then I had to take the trailer back to Tims and the van back to the place at Birmingham total was about another 5 hours or so...
Was it worth it- to be honest after all the fucking about with the car and getting it mot'd tax'd insured and all the work the NMS guys did- not in the slightest.
I prob wont do anything like it again
