As Steve reported,
http://forums.tipec.net/viewtopic.php?f=35&t=8643, I rather nervously drove away one of his 944's last night.
I was delayed getting there so the first experience of driving a 944 on my own was in the dark with torrential rain: should have checked which switch was for the rear wiper

before I set off but at least the main wipers and lights worked OK...so that's a bonus!
Unsure of the steering lock and paranoid about hitting something, it took me a 10 point turn to reverse into the garage but daylight and a 40 minute run this morning have replaced nervousness with a big grin.
Looks as though the only mistake so far was not taking up the 2 year membership offer at Gaydon on Sunday but there again....three days ago I didn't know I was going to become a Porsche owner!
