By the numbers... Assuming a 12000 purchase price.
Paying Cash:
Cost of sled $12000
Market Deprecation value %20: $2400.
Money owed: $0.
Money invested elsewhere: $0
Dollars regained when sled is sold: $9600.
Total loss over 1 year period: $2400
Finacing 0%
Cost of sled $12000
Market Depreciation value %20: $2400
Money owed: $200 a month x 12 months = $2400
Money invested elsewhere: $10,000 @ 9% yearly return
Money MADE on investment: $938
Total payments on sled: $2400
Total amount paid to bank after sled is sold: $9600
Total recouped using money invested: $938
Total lost over 1 year period: (12000-9600) - 938 = $1462
FINANCING AT 0% AND INVESTING COULD SAVE YOU $1000 PER YEAR
So keep telling yourself that paying cash is better than financing... Fiscally smart people will take the 0% EVERYTIME over paying cash. You can invest the cash elsewhere at a standard market return rate and actually make money instead of just loosing it.
*disclaimer: not all peoples sleds will be worth $9600 at end of year, some worth more some worth less. not all people will qualify. missing a payment incures all interest at market rate to be applied to loan. Must payoff loan balance before year of 0% interest is up.
