If you're interested in how much it costs per month, let me tell you how you can buy a brand spanking new, fully loaded X5 4.8 for only $1 per month. Put about $75,000 down.

Seriously, never negotiate a price per month. There are way too many variables. Buy, lease, good/bad credit, finance rate, $ down, mileage on a lease, etc. Asking how much a car costs per month opens you up to those shady dealers with horrendous 84 month loans at 10% financing. Makes you sound like you either a) don't really have the money or b) don't really want to buy the car.
