This might be an unpopular opinion, but does Lily REALLY need a car or even an electric car? Or does she just want to feel superior to other people and avoid the congestion charge?
It’s not like she or Rich are commuting outside the city for work, they don’t go away on weekends, families all over Europe successfully travel on public transit with their kids, they get their groceries delivered, they live in a well-served area in terms of amenities. If they needed a car for their 1 trip to Suffolk a year, they could borrow a family member’s or rent one like the rest of us plebes.
