free 1.5 hr tours led by a passionate car enthusiast. i was surprised about the amount of folks (a few from out of the country) that were on the car tour on a weekday morning. the place is clean and open and they have lots of gorgeous cars to look at. if you go on the tour you can go into the factory but can see everything that you'd encounter on the tour by just doing a self-tour. at the end of the tour you do get to sign your name with sharpies (provided), which was kinda fun. i learned a lot, some cool souvenirs, good spot to go if you're a car enthusiast or like nerdy factory tours for me but if you're limited on your time in las vegas then do more typical vegas activities back on the strip. ;)
