200 miles really is not that far
I would arrange to go see it, with purchase in mind..... in the mean time go round as many dealers as possible test driving a few so you get the feel (same year/spec/model if possible)
At least then when you drive the one your looking at, and its a rattly old bucket you know to walk away.
+1 on seeing if a forum goer can check it out first
Good luck and I hope its the one for you
