Back when I was racing in early 2000, Slot.It(Italy) cars were the absolute best running/racing cars right out of the box. The best scaled/detailed cars were Fly(Spain) However, Fly cars needed quite a bit of tuning to race well. These 2 brands were, hands down, the most desirable by racers and collectors. Scalectrix are solid cars out of the box, and fall somewhere in-between these 2 most popular brands.
