<prompt> Human: There is so much great advice on this sub about how to get out from underwater on bad car notes, how to fit basic transportation into your budget, and how to make a 5000 Camry fit into your life and budgetary future.However, theres very little in the way of buying a brand-new or late-model performance car without killing yourself financially.Within the next year, Id like to buy an up-optioned Mustang GT with the Recaro seats and performance package, or a comparable Camaro. In the case of the Mustang, that means 2015 or newer because for my motorsport of choice, I need the independent rear suspension to be competitive. Camaros, Id have a bit more leeway since theyve had IRS since 2010, but the 2016 models make so much more power that Id be a fool to go older.So this is going to be expensive. Like over 40k.I make a little over 100k a year, and I plan on putting at least 10k down, because Im terrified of being underwater on a car, plus itll keep the payment manageable. I pay about 1500month in rent. My current car, a 5000 beater, costs almost nothing to insure. Im fully funding my Roth IRA and my 401k.I already know that wheels and tires are going to cost way more than the ones for my beater, and more often. I know insurance will be a lot more, and I know Ill be jumping from no payment to having a big payment.Im willing to accept that Ill be spending more on my car than is commonly advised, but its not just transportation for me, its motorsport - so its hobby spending, not just basic-necessity spending. And before anyone raises an eyebrow about racing a financed car, 1 its just autocross in the US definition of the term and 2 if I do track days, I live in Texas, where Ill actually be covered by insurance in the event of a mishap as long as its just an open track day and not a competitive event.So: what am I missing? Whats the big killer thats going to make this turn into a bad financial decision? On paper at least, as a hobby and not as a basic need, I can afford the car.And if Im not missing something, whats the best way to get a good deal?  <response>: Youre better off posting this on rautocross or something similar. You know your going to buy it, just need to know odd expenses.
