Is this a good lease deal for a loaner 430i convertible?

Hello, a local dealer is advertising a previous courtesy vehicle 2025 BMW 430i convertible for $628/ month without tax. The down payment with loyalty rebate is $4,888 with 7,500 miles per year. The vehicle currently has 6,650 miles and the asking price by the dealer is $51,745. The original MSRP is around $61,695.

The spec is everything I am looking for but what would be a good monthly payment be? I will qualify for loyalty and I will need 10k miles per year? Any help would really be appreciated.

What’s the total amount DAS (due at signing)?
