Going for a Mini test drive tomorrow, need some advice..

‌I'm going for a test drive of the Mini electric vehicle tomorrow as one of the candidates to replace my wife's car.
I've bought several cars in the past, but I've always just looked at catalogs or sat in them at the dealership, so I don't have much experience with test driving.
What should I focus on?
I personally think checking the ride comfort and how easy it is to drive should be enough, but...
