People buy 100k cars online nowadays, why wouldn’t a great online presence also work?
But I guess 100k cars are bought are bought more in person than 10k cars. For most people, the more money you spend, the more you'd like to talk to a real human being.
A 100K car is a commodity product with very limited customization.
If you don't like the car, the manufacturer is not going to make a new one for you personally.
A large SaaS customer is the opposite.
