When I bought mine I wanted manual, didn’t want satnav, idrive, adaptive lights, comfort access, parking sensors, or a lot of the other stuff. I wanted a basic drivers car.
I can adjust the seat myself and no one else drives it anyway. Not interested in fancy sound systems.
So, as you can see, what you define as budget, I define as simple, less to go wrong and still the same fun to drive.
It really boils down to personal taste, so telling someone to avoid a car because it’s low spec could stop them seeing the one that actually would have suited them.
