The only way I see it working, especially with the required two visits to the dealership’s, is a few people in the same area want a car from the same dealership. For example we got our xc40 from Taggerts in Glasgow, Karen, another member of the forum got her, same day, from the same dealer. If a couple of other members, in our area, wanted to get their car from the same dealership we could got together and tried to get a discount.
Nobody is going to travel a far distance for a couple of hundred pounds so you need-:
1. Members in the same area
2. interested in cars from the same dealership.
3. All being able to order at the same time.
