Adam I have just bought my zed from pics and talking to the guy only, had to send a £500 deposit to hold it , was a 3 hour train journey to get it and a 3 hour drive back but was deffinately worth it .you tend to get a feel if buying the car is right by talking to the buyer in detail and plenty of pics. My advice would be to book a one way train down and go as if you where deffinately buying the car to bring it away, if the car is not as described or your not happy it's the cost of the train back, but I would be confident that the car is spot on and well worth the journey!
Get a return, it's only an extra £1
I'd travel anywhere to get the right car. Went with a friend and traveled from portsmouth to wigan to get her DC5. I'd happily drive to Scotland to get the perfect car.
Downside = You don't know what the actual version is compared to images/comments etc.
Plus Side = The awesome journey home in your new car.
