The financing of an asset you own doesn't effect the appreciation or depreciation of said asset. The decision to pay cash or finance depends on your cash on hand, cash flow, other debts. If you don't have the cash on hand, but easily have the solid cash flow to handle payments and other debts, there's nothing wrong with financing the purchase. Sure you could wait till you have the money saved up, but you would be missing out on several years of enjoying the vehicle...the opportunity cost. If that cost is meaningless to you, that I don't know why you would buy a Raptor anyway, since you could met the basic need for a vehicle much cheaper.
I think the main point was though that even if you do have the cash on hand, if your interest rate is lower than the rate of inflation and/or whatever rate you get by investing in something rather liquid, you're not maximizing your money, making it work for you. That's fine, it's the safe route, but it is not the best route.
Where people run into trouble is the get into more debt then the can comfortably handle given their cash flow. It's not that you can't make large purchases, but you should wait till you have enough cash on hand to make it reasonable. And your cash flow should be steady and reliable. If your job means you get large payout at irregular intervals, or you're relying on your mother's SS check as income, then wait and pay cash.
