Because people are bad with money. Drive through an apartment complex and then drive through a neighborhood of starter homes; I'll bet the former has nicer cars than the latter.

I've seen plenty of $35k+ cars in ghetto apartment housing. People seem to look at the monthly payment instead of the total cost of the car can never seem to get enough saved to buy a house.

I don't know which is the main buyer of higher end cars, but they shouldn't completely discount people who prefer to buy cars than save for houses.
