I'll let others comment on the lease deal itself, but looking at the sales price, while it may not be the lowest out there in the area, it should be considered at least a "fair price" if you believe the pricing info from sites such as edmunds and KBB. The prepaid maintenance is definitely a ripoff though. It shouldn't be higher than the MSRP posted on MB website. So for GLC 300, it should be no more than $1335 for 4yrs/40K miles.
