How much is my brabus?

Hello, I just recently received a s500 2003 brabus but I don’t know much about these cars. I haven’t found anything online about this type of car so I was hoping to post here and to see if anyone knows how much a car like this would go for.

Details
-Year: 2003
-Model: s500
-Mileage: 130k
-Clean title
-Brabus modified

If anyone has any questions I will try to answer to the best of my abilities

Thank you!
