HI all. In trying to fill in the 3 months until my GTD arrives (

) I was musing through the price list and something stuck me as a little odd.
Due to the ongoing debacle over whether Lane Assist is available or not, I was considering deleting the pack altogether and replacing it with leather (which the wife prefers over the plaid cloth), which would also mean I'd be able to remove winter pack as well (as the Leather comes with heated seats. So removing them two would save me £870 (£520 + £350), so I thought I'd see what the leather came in at.
Surprisingly whilst still very expensive, it struck me as a little odd that for the SE and GT models, leather is a £1,830.00 option but for the GTI/GTD it's "only" £1,675.00 (£155.00 cheaper). Anyone know why this should be (not that I'm complaining of course - still too bloody expensive). Suppose it's too much to ask that UK spec models get the Alcantera / Cloth seats and so upgrading to leather is slightly cheaper, or is this just another VW UK anomaly ?
As it happens, I've decided to keep the cloth anyway, but still wondered why it's cheaper ?
