I decided to purchase a few of the new DLC items in online.
The Stirling GT is wonderful, its now my favorite Sports Classic followed by the Casco. It sounds amazing and feels very light and planted to drive around in, I kept it stock and its great. Mine is silver with chrome wire wheels resembling that of a Mercedes-Benz 300 SLR. Its also very affordable in-game considering its real life counterpart is worth a fortune, it came in at $950,000.
I also purchased both of the new aircraft. Together they came in at $15,150,000. The golden Luxor is my favorite, it can withstand 3 homing missiles before going down, has an illuminated interior with champagne and cigars present for your own entertainment. You can choose to sit in the back or the front, and I've been having people fly me around in it in exchange for letting them try out the new cars. A lot of people think they are very expensive so I often get asked to test drive them as people want to make a confident purchase.
