Happened to another person as well. I've seen him in Michaels Car, F620, and a Jackal. Usually he's in his Sentinel.
The same guy's been spawning in a Sentinel XS for the thousands of times I've seen him speed by. Never really saw him in any other model. I wish he'd drive a regular Sentinel. I've spent so many hours on my Xbox trying to find a regular Sentinel Hardtop Convertible. :c
IDK, but I saw an Entity parked the block from the Rockford LSC. I was also in an invite-only by myself.
The Entity seems to spawn every now and then. It's just that I never, ever saw or even heard of a random Stinger GT appearing. And I always notice stuff like this right away. GTA-addict, haha~
I only seen 2 crazy cars, bagger and sentinal
Bagger seems pretty rare, though they like to spawn every now and then when Simeon asks for one. I have one myself, looks gorgeous when modified~ I still want a regular Sentinel Hardtop Convertible. I've already seen a million Sentinel XS and Zion Cabrios. Hell, even regular Zions with hardtops. (Not convertible.)
DAMN YOU, SENTINEL. I WILL FIND YOU!
I wish I could help you with your search, but I'm on PS3
