Chad Johnson: Environmentally Safe Swag ... Drops 25k To Pimp Smart Car

Chad Johnson is proving that a small carbon footprint can still leave a huge impression ... 'cause the Ex-NFL baller just made his tiny Smart Car a big eye catcher ... dropping $25k to pimp the mini ride.

We're told that Johnson wanted his ride to pack a little more punch so he took his 2016 Smart Car down to the Auto Firm in Miami where customizing master Alex Vega went to work on it.

How do you make a Smart Car look swag? How about plastering it with custom satin black paint, throwing some Av30 forge rims on it, plus tossing in an Avorza grill and body kit.

Final price tag $25k.

BTW the Smart Car with all the trimmings, retails for a little over $18K brand new ... so Chad's proving there's no price too big for mother earth.
