Unsure of lease or financing, should I get pre-approval either way?

My wife and I have begun car shopping however we're unsure if we're buying or leasing. I was going to get a preapproval from my credit union before we started talking to dealers. Is it worth still getting a preapproval if we end up financing? Does that still give us an advantage in negotiating?

A pre-approval can also help you discover any deficiencies in your credit report, instead of being surprised at the dealership.

That time period may vary slightly from one credit scoring system to another but typically is 14-days."
That's per Experian but I think that's the general rule of thumb.
