I belive that it's an Altezza or IS200/300. The image quality isn't so good so it's quite hard to tell.... If you look at the side of the car, you'll probably recognize the familiar lines of the IS300.
seems to have a Yellow IS300 (you can see the roof and door as the camera follows the drag race).
That car in video3 _might_ be an IS300/Altezza, but I can tell this:
1> It has an aftermarket front air dam
2> It appears to have a banner across the top of the windshield.
3> I don't see the red rear lights on the trunk lip.
Here is an image showing the car in the video next to a real IS300:
I haven't downloaded the video but if you guys go over to www.autobuzz.com in the Autoshows gallery there are pics from Redline the movie...on page 4 the second pic down is of a Black IS300 with a wrap aroud spoiler and the Cal. License plate Alteza...which I thought i remebered someone in here saying they were gonna get but anyway hope that helps
