No, your math is right. The $500 per month figure is for the 85 kWh car, which is more expensive. Tesla's "calculator" gives roughly the same figure as you for the 60kWh car. That doesn't mean it's comparable to a car payment of $351/month though. If you did equivalent discounting to a car that only had a $351/month payment (maybe some sort of Kia?) then that would come out to be in the ball park of $150/month, but you don't see Kia advertising their cars like that.
