Hey Neil,
If you can negotiate enough money off to fix the issues, then go for it. The car sounds like it's pretty good, but only you can decide if it's the one for you. Bear in mind they are all 5yrs old now, so minor issues should be expected. Both Stu and I have things we are going to address on our cars, but nothing major.
The edges of my doors, and the top of the rear bumper needs paint on mine. Not sure if the rear screen was replaced at some point, but might explain the scratches?
It's all about what you can live with mate. Mine is here to stay, so I will work my way through the little niggles to get it up to my standards. When it's finished, I will know its all been done properly at least.
See what price you can get. If it's not good enough, walk away and wait for another one. Just keep in mind that may be as bad, or possibly worse?!
May struggle to find one with such low mileage?
Best of luck with whatever you decide.
Cheers.
Peter :)
