Well - just a small update...
Have just returned home after a week and a 1000 mile round trip to Wales (and the environs), I can happily report that the 'old girl' didn't put a foot wrong.
Driving in Wales is a VERY DIFFERENT experience to driving in Norfolk and I have been introduced to a whole range of different creaks and noises - whilst these somewhat played on my paranoia, driving along at motorway speeds was a dream, so I'm assuming all is well for now!
I am planning to have her checked over prior to the MOT coming up in November as I have absolutely no point of reference as how things should sound and feel. I maybe suspect that the front diff is a bit whiney but I'm not sure?
I reckon to have averaged about 18 mpg which I'm mightily impressed with, given a roof rack and box, 4 passengers - all over 6ft, and 2 dogs! The fuel cost more than the holiday cottage accommodation!!
Hairiest part of the trip was a 'magical mystery tour' initiated by SWMBO which included a 6ft 6" narrow hump back bridge - photos to follow!
