If I put that amount of money into an account that could earn on average 10% per year for 25 years, I'd have somewhere around $450,000.
I decided to buy a $3500 car at that point.
No offense, but your knowledge of finance is a bit whack. For example, you're comparing a 5 year cost against a 25 year investment. $430 * 300 months (25 years) is a lot more than $25k (it's $129k), so your very premise is apples and oranges. Next, $430/mo. on $25k for years is not 6% interest, it's 1.25%. Moving on, that $450k return would be at 8.5%. That rate of return is far too aggressive to be a savings account, and you're not taking into account any risk -- something to think about. Finally, you left out operating costs and service life on that older, cheaper car, which is certain to be considerably more and shorter (respectively) than on a newer car. The cost of a car is more than just the initial acquisition cost.
What I'm getting at is that, provided the rest of your financial picture looked good, it could have been very reasonable to invest in the car for the first 5 years, then into your actual investments the next 20, and get a similar rate of return. I'm not knocking your priorities, I'm just saying that your statement was too simplistic and not "big picture."
edit: In the "business of life," cars (transportation) are not investments, but they are overhead.
