The display is Ikea's Detolf (5 of them, actually, side by side). They sometimes go on sale for $50 each, but normally I think $65. I am a car nut as well, and had some 1:18 scale models. Many people use them for the cars and even figurines.
They have two types of lights that go for $30 ea (4x lights, 1 per shelf). They have a dome shaped light and an LED strip, which I have. Ikea's lights use to be a cool blue LED, but recently changed to a warm yellow gross output. I'd have to see where I got mine, but the 2nd and 4th cabinet has Ikea's old bright white/blue LED's and, the cases on the ends and in middle (1,3,5) are from some other website I came across. Even brighter than Ikeas if you look hard.....
Overall, ~80-100 per cabinet w/ lights, and I have 5. Also, people but small U-bolts and get glass panels cut at a glass place to add shelves to the Detolfs. Google search it
