KSNV Las Vegas reports Vegas Auto Gallery has sued Floyd Mayweather Jr. in an attempt to collect $1.2 million for a 2018 Mercedes-Maybach G650 Landaulet SUV, one of four vehicles the boxing legend acquired from the dealership earlier this year.

Mayweather ultimately returned three of the vehicles but agreed to pay $1.2 million to keep the G-Class, according to the lawsuit, which notes a Sept. 1 deadline was extended to Sept. 18.
