This week's GTA Online bonuses and additions include the Dewbauchee Rapid GT Classic

The latest GTA Online update adds the Dewbauchee Rapid GT Classic car, alongside numerous bonuses and discounts.

The new car has "matured like a fine vintage wine", apparently, and is "deeply customizable", according to Rockstar's post about the new car. It's not available for purchase in-game from Legendary Motorsport, if you're looking for a new vehicle to show off in.

The double payouts currently active in the new Motor Wars mode are also being extended until September 18. You can also earn double payouts in the Stunt Races that Rockstar has created for the game, so if you're a good dangerous driver you can reap the rewards right now. This is also true for Smuggler's Run Sell Missions.

It's also SecuroServ Employee Appreciation Week, so "Bodyguards and Associates receive Double GTA$ salaries".

There are also discounts on certain vehicles and upgrades. There's 25% off countermeasures for flying vehicles in the Hanger Workshop right now, giving you the tools necessary to dodge assaults, and there's also currently 25% off Aircraft Engine and Armor Upgrades. You can also save 25% on the Truffade Nero and the Pegassi Tempesta, plus 25% engine and armor upgrades on all cars.

The premium race and time trial schedule, live from now until September 18, includes the Premium Stunt Race 'Big M' (for motorbikes) and the Time Trial 'LSIA'. These can be launched via the Quick Job App in-game.

Basically, if you want to upgrade your vehicles and then test their limits, this is a good week to jump into GTA Online.
