The problem with having a luxury car is that people will get jealous and try to key it/damage it in some way. Also, you may get some unwanted visitors. A man walked out from the store to see a dad filming his two kids dancing on the hood if his. He politely asked them to **** off but the dad went "Wait, let me finish recording".
I don't mind others having them. Everyone has their interests. No need to get jealous, of course. Most people with luxury type items work very hard for them.
I'd like to have one but there's a lot of drawbacks to it.
