Grand Theft Auto V - GAUNTLET LOCATION: PILLBOX HILL
There are THREE locations to find parked Bravado cars. Lester sends an email with the location and the photo of where it can be found. Fortunately, jacking the cars won't incur any Police attention so just grab the car and drive away.
GAUNTLET LOCATION: PILLBOX HILL
The first car is found in a parking garage in Pillbox Hill. The gauntlet is on the roof of the parking structure so drive up there and take the car to LS Customs.
