Cash is no longer king when it comes to buying cars. I've bought using all methods, cash, lease, pcp, bank loans and balanced payments, There is no right or wrong, you just need to know how they work and use what best suits your situation at the time. If your eating beans on toast everyday to pay for a car then you obviously can't afford it, if you have a healthy income then I see no wrong in using finance so long as it's a reasonable interest rate.
