Leasing a BMW can vary depending on the specific model, trim level, lease terms (e.g. lease length and annual mileage allowance) and promotions available at the time. As of my knowledge cutoff in September 2021, here's a general range of monthly lease payments for popular BMW models:
BMW 3 Series: Around $450 to $600 per month.
BMW 5 Series: Around $600 to $850 per month.
BMW X3 compact SUV: Around $500 to $750 per month.
BMW X5 midsize SUV: Around $650 to $1,000 per month.
Please note that these are just ballpark figures and actual lease deals can differ based on factors such as personal credit history, location, optional features added to the vehicle, and current incentives. It's best to visit a BMW dealership or use online car leasing comparison tools to get the most up-to-date and personalized lease offers for your preferred BMW model.
