I like it. The others are right I think, the red hose up front doesn't looke that good. On the other hand, the hose you put there instead is to easy to miss. Perhaps some ribbed hoses in silver would be better?
I hope you're not planning on using the PF Speed controller on that thing because if you do and the signal is lost, the car will just continue to run with no way of stopping it before it's too late - Especially with the buggy motors attached.
