Which Would Be Better: Buying Vehicle Outright or Credit Union Auto Loan?

I (24 y.o.) will be purchasing a vehicle within the week, and the 'out the door' price is +/- $23,500. As it stands, I can comfortably purchase the car in cash and avoid having an auto loan. But I heard that having a regular payment is good for building credit. I would appreciate any advice on what would be the best decision to make.
