Simple 03 E320 Question

[Dave M]

About a month ago I sold my 98 E320 and and yesterday bought an 03 E320. I tried to look the car over thoroughly. The car seems straight and tight but I made an obvious oversight when, after I had paid for the car, noticed it was missing a front license plate bracket (required where I live). The lot where I bought the car said they would take care of it but, after calling a local MB deaer in the area and finding out that the bracket is about 60 bucks, I'm concerned that the used car lot where I bought the car will try to renege, or scab something on the car that is inappropriate. I also noticed there are no apparent holes in the front bumper/shroud for a license plate bracket. The question is "does the front license plate bracket clip on the front bumper or do holes need to be drilled in the bumper"? Also, is the bracket available for less than $60? The MB dealer I talked to needed the VIN number of my car to establish the correct part saying there were 21 different license plate brackets available. Thanks for any help.
