Two people injured in Kevin Hart’s vintage car the night it crashed have lawyered up and plan to sue the comedian and the body shop that customized his muscle car.

Hart was a passenger in his 1970 Plymouth Barracuda driven by his friend Jared Black who lost control of the vehicle and veered off the road just after midnight on Sept. 1.

Both Hart and Black suffered serious back injuries in the crash, but Black’s fiancee and Hart’s personal trainer Rebecca Broxterman, who was sitting in the back seat, was not seriously hurt.

According to TMZ, Black and Broxterman have lawyered up and plan to sue Hart and the body shop that modified his car.

Broxterman and Black say Hart is negligent for failing to install standard safety features in the 720 horsepower car.

Hart reportedly didn’t want safety features such as air bags because he wanted to maintain the car’s 1970 authenticity. Airbags weren’t standard equipment in all cars until the 1990s.

Broxterman and Black also plan to sue the bodyshop for going ahead with the job despite the car having no safety features.

Hart returned home after spending a week at a rehab facility. He underwent surgery to fuse his spine. He will receive physical therapy at home.
