Going into debt to buy something that depreciates the moment you take it out of the shop is just not good money sense, and especially so if the interest on the debt is non-deductible. Perhaps young folks don't consider these things when they make such purchases. I was speaking with someone at a party on the weekend who paid $42,000 for a one-year old Nissan Z3.5. He was maybe 25 y/o and living with parents. Do you think he thinks about cared whether or not the debt was tax deductible? And I sort of get this--this was going to be his chick magnet! Could the same be said for a bike? Any bike?
