New to leasing needing a little help

,

Autonation BMW dealership in Houston just emailed me this lease worksheet after checking out other x3 deals this one doesn’t look anywhere close to what i was expecting. It’s a demo with 3,xxx miles on it

From what I have been looking here in the forums this doesn’t seem like a good deal, especially after seeing someone getting 379 per month on I believe 12k miles per month and no down payment in the same model you have. I’m also trying to negotiate with those guys here in Houston.
