@Steve Vaughan I "feel" just fine knowing that I financed my 25k car at 2.99% and I have a dependable car to get me to work and my investment houses. I live in the country so I am 45 minutes from town and my rental house. I have always driven used cars and pushed my fair share of cars off the road when they stalled out. And in 10 years when my Subaru has 250k miles on it and smells like blood, sweat and tears I am sure I will have gotten my money's worth.
My justification is this: If I Pay Cash for a $7,000 car every 3 years - I drive a lot and have worn out 2 used cars in last 6 years... Then I have 21k tied up in cars. If I ever need to use any of that 21k for repairs on rental, down payment or closing costs on an investment house, I can't even begin to borrow that money at 2.99%
I believe keeping the money liquid for investments is better than paying cash for a new car or multiple used cars. The best things about a new car are better interest rates, warranty for a while, and you can keep it maintained. If you keep it until it is worthless you get all your money's worth. I chose a Subaru because it has the best maintenance reviews and it can handle high miles.
So if there is something that you can finance for a low interest rate, do it!
I also have financed a roof for my rental house for 5.99% interest on my Lowes Card. This way I came up with none of the money for the roof and the cash flow pays the payments. - - Leverage isn't always a bad thing. Debt is only bad if you have no plan to pay it back.
