Provided vehicles

Are there any officially provided vehicles for these races? I've only done Shift Work, but as soon as I started the mission, I noticed there was a red Ruiner on the sidewalk near me, which I hadn't noticed before. GTA IV has several missions where an advised vehicle can appear parked near the player at the end of a cut-scene.

Anyway, I completed the race with another Ruiner from my garage. GMRE (talk) 21:23, May 2, 2015 (UTC)

Nevermind. Someone has already reported it. GMRE (talk) 21:43, May 2, 2015 (UTC)
