I built this model. It's not that hard to build, but I modified it a little to make it more realistic. I printed some strips that resemble turbo lights and put them on the light bars that angle up under the top, put rods under the bottom edge of the top for the light bars to attach to, made a tongue with a control box, and lifted the top up about 1/2 inch so it wouldn't be so close down on the cycles.
The cycles are a pain to paint because they're so small, and a couple of mine weren't completely molded, but they look OK after painting. I also thought it was a pain because you have to drill a small hole in the back of each cycle to insert the sweep.
Once I had it finished, it's not bad looking.
