And just to go for the obsessive poster award, one final thought:
NOTHING destroys your money and net worth like a big shiny brand new car. It is about the worst thing you can do for your financial health.
I get this but some people like new cars. Booze and vacations aren't good for my financial health but I buy and take a lot of them. Because I enjoy it and I can afford it. Could I take the thousands and thousands I've spent and save it? Sure, but that's no way to live life.
If you like new cars and can afford the car, buy the damn thing.
