I’d definitely not be accepting a car without adaptive cruise control, You have done the right thing.
I could not have a car now without it, It’s one of my non negotiables my last 4 cars have had it and when I drive a car without it, even with normal cruise it’s worse for my condition. The car I got, just joining the scheme, it can as standard.
Maybe one way to guarantee it does, is to order a car/trim level that it comes as standard and not an extra.
This stuff shouldn’t happen though.
