This isn't about a car. It's about a spouse. And it's about committing to a lifetime with that person in marriage.
Half-arsing it by living together first is just dumb. It sets patterns and creates lowered expectations before the marriage. Now flame away, but I'm being judgemental on this one.
Go for it! Nothing wrong with that, especially when you've got your stuff together.
More than a third of married Americans (37%) say they lived with their spouse before getting married, while 63% say they did not. In 1988, just 19% said they lived with their spouse prior to marriage and 81% said they did not. [Dec. 27-29, 1988; Jul. 22-24, 2002] Gallup
