Freeman, mine went like this...
no interior, not wired in and working, no bonnet etc...
they give is a quick check over in terms of engine number and chassis number and thats it. About 10 minutes in Poole. Then again, Mike did say recently that they made a load of redundancies in Poole, so I am not sure what will happen now. I will take my Miglia Speedster down at the end of the month and let you know as it is the same process.
