Any experience with lease auto brokers? Best audi deal

I am getting really good deal on 2016 Audi a4 premium quattro. 350 per month with 500 down for 10000 per year for 3 years. I don’t know how did he make this deal but it is first time I am getting car. Also first time dealing with auto broker. He said he will deliver the car to my home and then sign the contract. Anyone wanna suggest me something about

  • should I go for that deal?
  • what safety should I use while dealing with broker?

I’d be interested to see the details of your deal when you’re all done. I’m considering an Audi in the near future.
