Vladimir Guerrero Jr. will be cruising into the MLB season in some serious style this year ... TMZ Sports has learned the Blue Jays superstar just got his Mercedes-Benz tricked out!!!
The Toronto first baseman took his GLE63 -- an expensive ride that he copped about a year ago -- to Alex Vega at The Auto Firm in South Florida to get the work done ... and it came out awesome.
Vega blacked out the vehicle -- wrapping it, before darkening its chrome emblems. He also upgraded its wheels too .
