I really can't believe that Rockstar hasn't done anything about the terrible vehicle system in the series. I mean, sure, a full-on save and spawn any car you want system like in Saints Row probably wouldn't fit here, but there's got to be a middle ground between that and "fuck you if you think you're going to keep any car for more than 10 minutes if you actually drive it." Maybe the impound thing was supposed to be the solution but it doesn't work; maybe 1 of 20 cars I've lost have given me a notice that they were impounded.
Personally, I think that at absolute minimum any car you actually buy from the website should go in the spawn list alongside the Elegy RH8 that they give everyone just for logging into the Social Club.
P.S. Has anyone seen a Sultan RS yet? I've gotten a plain Sultan, but I'm hoping that it's like GTA IV and the good version is out there too. It was by far the best car in GTA IV imo.
Edit: Nevermind. If you put a roll cage on a stock Sultan it turns into a Sultan RS. Which sucks because modding cars is pointless when you just lose them the first time you drive them to a mission.
