If you've got (more than) a few extra bucks in Grand Theft Auto V Online, you should consider splurging on the new Progen Itali GTB Custom that was just released. The car, available from Benny's Original Motor Works, is a fast and maneuverable vehicle that allows for customization of anything from performance to tiny interior details.
If you're an Executive with access to the new Import/Export garages, that's not all. There's a Custom Auto Shop add-on that allows you to fully upgrade and customize your vehicle without even leaving the building. Yeah, it's not exactly cheap to become an Executive, but all the perks like this one make it worth it if you've got the time and money.
Also, don't forget that last week's Online bonuses are still up, and will remain through January 16. Take advantage of these before week's end:
