Yes, that is true....how much of a percentage of your paycheck are you willing to pay? How does that make your tax due any less? Essentially, you're just paying more over time....I'm old enough to remember being single and getting a tax return in the thousands of $$$, now I'm married with a child and I owe money...
On a side note, I'm also old enough to remember when a car loan for 5 years was the norm....now we're at 6, and the max for a mortgage was 30 years, now we're heading to 40.
