Seconding Tyler's point, but with a slight amendment.
Paying cash is generally[] not better than financing through the dealership, but is much better than bringing your own financing.
[] There are a couple more factors that I haven't seen mentioned, specifically that paying cash is generally a lot faster. For the dealership, there isn't necessarily a benefit, but for the salesperson, a quick sale means they might get to slot an 'extra' sale in for that day, so it's worth it to them to play around with their commission on what they might consider a 'gimme'. If paying cash, it is best to do so on busy days so that there are other 'fish' for the salesperson to go to next. If you're the only person there, there's no real sense in urgency.
