I paid for mine 50% Cash 50% Finance, 4 months interest free, i kept 6k sat in my bank and gained a little more interest, 3months later i paid up the final fee that "Interest Free" wasnt the case, i had to pay an admin fee and then a final settlement fee.
If you can, buy outright.
Handing over all that money is butt clenching for me, i hate spending money.
