Well done, Mark, and welcome home to Joseph.
Gave the GTS a good wash today and replaced the front tyres with ones which have - shock! - tread all the way across. Also replaced those notoriously rusty underside pipe protectors for shiny new not rusty ones. Gave it a general clean up underneath and some underbody sealant round the area as well. I must say, the car looks a million dollars. Well, maybe not quite that much. (Although if anyone actually wants to offer a million dollars I'll ponder it briefly before accepting, with grudging thanks.)
