Result for you!
When I was negotiating a deal for a 5 door GTi with DSG and quite a few options, I put into the equation:
OEM rubber mats
semi-rigid load liner for the boot
Jewelbrite/Diamond brite coating for exterior and interior
all free of charge and this was agreed.
Furthermore, we have also secured a first free service, as the dealer had to recode one of the keys (which took all of 1 hour to get there, recode and get back home).
Best of luck...
