I ordered an Ateca in October 22 as my first Motability car and have had the date moved twice already due to issues getting DSG gearboxes. I now have a build date of 4th/5th May as confirmed by the dealer this afternoon. My order is for the 2.o diesel though, which does still show as available on the Seat website.
I did approach VW for availability of their Tiguan as either a Motability or private sale and was told 12 months plus lead time for the 4 wheel drive version with DSG.
Originally scheduled for early Feb 23 delivery my car will hopefully be delivered 4th week of May. I had strongly considered buying something else privately but the Motability scheme includes insurance, servicing and tyres so will hopefully prove beneficial for this 3 year period. My wife has just ordered a new Volvo XC60 with a 4-5 month lead time but got £12k off and 0% finance as an existing Volvo owner, plus 5 years servicing for £1,149., so there are deals to be had out there.
