A lot of it will be dealer specific if not group specific.
Salesmen cost money, their time is literally money.
If sales are down (in pure ££££ terms as much as number of cars shifted) then dealers will adapt a style of selling to try and win sales.
DtD dealers have it easy, they just have an order over the internet and likely still punt it through the fleet department to make the most of the higher discounts available to them. But to make that work you need a good fleet department and not all dealers have the luxury of this. Smaller rural dealerships or towns and cities in the shadow of a major city with big dealerships with a lot of clout with VW will have a different market to have to endure which is a bit more old fashioned.
If I walk into my local dealer, which is a big dealer with an ultra-modern showroom and a huge turnover, I immediately feel like a fish out of water. Glance around and you'll see slightly overworked sales execs trying to be charming to middle to older aged well healed couples who don't really know exactly what they want, what options are offered and nor to they know what the real trade value of their own car is. They'll sit there and listen to the sales exec for a while, ask stupid questions and then say they're just off to test drive a BMW and a Ford and if they still want a Tiguan or Golf or Polo or whatever then they'll be back to see if their golf bats or other sh!te will fit in the boot. Then there will be the old lady who quite obviously hates salesmen with a passion and totally mistrusts the car trade in general, having suffered Arthur Daley types in a younger life, trying to buy a Polo for either themselves or their teenage grand daughter getting completely baffled by how a PCP works.
And boy are there a lot of people who don't really understand what a PCP is.
Stuff all that, I just walk out again without speaking to anybody having been overwhelmed with cynicism, hit Carwow, online contacts and look at the broker prices to work out realistic cost to change over headline discounts.
Bigger dealers will have a dedicated salesperson to deal with Carwow or Orangewheels for people like myself.
But smaller dealers can be worth persevering with if they're a bit more old school and the sales manager wants to hit a bonus.
I've tried it all over the years, you just have to do your homework.
