SELL my PORSCHE GT3 for a BMW M4?! 

I think most people would agree that the GT3 is a much better sports car than the M4. I wouldn't mind having either car to enjoy content with. If you kept the GT3, you could make videos of yourself driving on winding roads, detailing it, taking it to car shows, meeting up with other GT3 owners, and comparing it to a 3RS or a .2 GT3. You could also provide an ownership cost breakdown, take it to the drag strip to race against other cars, or have a track day with it. Modifying cars is fun, but with such an excellent car, you can create many interesting videos.

Hey Benji. When are you going to upload content again? Greetings.

Tons of content for M cars already, I think. Porsche GT cars, not that much IMO.
