What features should all 75 and ZT's have came with but didn't?

[Robson Rover Repair]

Been thinking recently about our cars and how have some wonderful features and conforts yet there are several things they are clearly missing.

For me the obvious list given the era of design and production would consist of would be as follows

Isofix brackets (as standard or a retrofit kit option)
Rear wiper (saloon, I'm sure it could have been done in a neat way)

Then obviously the dreams would be

Hatchback varient - 75 meets sd1 / 800 fastback
Coupe varient - goes without saying

So question is, what do you think is fundamentally missing from our cars, compared to other cars from say 2000 onwards?
