Cash in full is the way to go, why pay interest when you don't have to? Sure you can build credit if you finance, but having credit cards would help you achieve the same thing. Just pay on time, keep the balances low, and good credit will come.
I paid more than 2/3 in cash and financed the rest through my credit union. I could have paid in full, but that would've left me with no cash for insurance and bills.
