Is this london one a dealer or private? 
 
If It was me, i'd ring him/her up and get them to walk round the car with you on the phone. 
 
Make a list beforehand of what you want to ask, like this...
 
FL wing
FR wing
D/Door
P/Door
LR wing
RR wing 
o/s/f tyre make, cond
n/s/f tyre make, cond
......................etc etc, I'm sure you get the drift
 
And get them to talk you round EVERY part of the car, including EVERY invoice/service stamp they have aswell. 
 
It will give you a good idea of the car without having to travel 150-odd miles to see a load of s**t and waste yours/your dads time. 
 
Thats what I do to customers that call from miles away and 9/10 they deposit over the phone as i've been completely upfront.
