We took delivery of a 1.6 Access 4x2 on Sunday.
Thanks to this forum I knew exactly where to look for any rusty bits and couldn't see any.
As soon as we got it home I fitted a new radio and speakers.
I found that the rear speaker wires didn't got all the way up to the radio connectors so stripped the B-pillar trims and door seals off and pulled the carpets up to fit speaker cables.
Thankfully I still couldn't find a mark of rust anywhere. In an effort to keep it like this I've sprayed inside all four doors, inside the B-pillars, around the tailgate hinges, around the child lock levers and various sharp edges and crevices under the bonnet with Wurth cavity wax.
I also sprayed some into the groove of the door seals (including the one above the doors) and painted some fresh clear Waxoyl onto the seams before putting the seals back.
When I'm off work next week it'll be going on a ramp and it's going to get a good dousing underneath too.
Seems a strange thing to have to do with a new car but I did a similar thing to the new Fiesta we got three years ago following the MOT advisory of boot floor corrosion on the three year old Ford Ka we were trading in. I admit it's faintly disappointing but it only took me an hour or so.
Fingers crossed for a none rusty three years or so of motoring.
