Sorry for delay in getting back to you. I don’t know, is the short answer. I’m hoping to get a half hour each at least. But with the caveat that I’m able get longer when I reduce my shortlist down to three cars. But we will have to wait and see. The good thing is I know if a car is going to be comfortable enough for me fairly early on in a drive. I have very specific needs which means if they’re satisfied then everything else is just a bonus (speed, mpg, badge, colour, interior design quality, features etc).
