ah, the Fusion... that explains that then!
Driven one once and it is a slightly mental bit of kit, verging on too quick for road use. I hit a tiny pebble and slid about 100 foot on it's roof
I had a Menace for a while, which has basically the same running gear but in a buggy chassis. Every time it changed gear it popped a monster wheelie!
I run this instead now, much more reiable and dare I say it more useable
