Purely by chance I thought I knew a possible location used for the car crash scene in Charlie Boy, near the end of the episode where Sarah crashes her white mini.

I took a drive there this afternoon after work to check it out and it was indeed the location, namely:

The Holloway, Whiteleaf, Nr. Princes Risborough. The confirmation that this was the location used is the house seen in the background as Graham drives away from the scene of the crash. The house has a distinctive gable window.

I'll take some photos when we have some nice weather and post them up.

Excellent piece of detective work. Surely not many locations left to find now.

I've started to grab a few screen shots, so as to update the episode pages which are lacking in information. I think a few new locations may come up.

Nice one Neal, Keep up the good work mate.....

cheers !
