Thanks guys for all the nice comments! Went for a quick blast and it is brilliant. Best thing was coming out my road and another golf passes me, you should have seen the look of the young guys face in the car. His jaw was nearly hitting the floor - priceless
I've had a good look round the car and externally it looks in very good condition however there are definitely quite a few residue marks on the paint (hope it's that cause it looks a lot like holograms from bird sh!t but I'm ruling that out as there is quite a bit). As a result I am now tempted to get a professional detailer to sort out. It is very expensive though, quoted £350 for a detail with ceramic sealant. I'm going to have to think seriously about this one because I want the car to have the best protection it can from the start.
