Well, one solution is to deck it out to the nines! A company called Aero 3S based out of Quebec, Canada, offers body kit treatments that will transform your reptilian 3-wheeler into something that looks fresh out of a Formula 1 wind tunnel.
The full (stage 3) fiberglass kit adds spoilers aplenty, large prominent fenders, a rear wing, -style scissor doors with windows and a windsheild made of Lexan, not to mention a hefty tab of $13,995 (or $29,995 if you prefer carbon fiber) on top of the $52,000 purchase cost of a T-Rex.
Aside from its bling factor, the Aero kit also decreases your exposure to the elements, making it possible for you to enjoy your T-Rex on days when the weather isn't perfect. The other solution to this problem... buy a car instead.
Aero 3S willingly sells all their parts piecemeal for your assembling pleasure or as a turn key unit for $67,995 ( shipping).
