The Scalextric Challenger is great fun, but it is taking a toll on my other slot cars. Its relentless, and if I spin out ahead of it - look out! Last night it took out my Fly BMW. Broken mirror, broken wing and the 2nd time it happened, it popped the drive train out. I'm not complaining. If I were a better driver it wouldn't happen. So far, 3 cars have sustained minor damage. But hey, that's racing.
