Hey, nice desing. Ya know, looking at this, you should have enterd Sanny´s custom car contest.

*Reads details* Good gravy, I'd be scared to live in or near the neighborhood that was charging around in! Twitch must spend a lot of time in the garage, puttering away on it.

To answer your question. yes! It is a garage queen but she has two other cars in case this one needs extended TLC. FYI.the engine is based on real engine that usually goes in a highly modified Suzuki Hayabusa motorcycle.

Get me one of those. It'll need an AC put in fisrt though

Yeah most cars in a furry world have A/C, but this one has none since it would've added weight and robbed power from the car. It is very bare bones.

I'm going to assume this is a modified Kei (K) Car, correct?

Yes and no. Where as a Kei car in our universe exists to exploit certain loopholes in motor vehicle law or to address urban density/ parking issues; this car exists because there is a large enough population of consumers who are just too small for many "average" vehicles. Therefore these are not cars that people over 5' tall are going to have a chance to fit into. The driving compartment is too smal. Unlike say a Smart which will transport two 6' tall adults ok. Finally this car was not design originally for the street but the track. Later someone figured out how to hang just required stuff on it so Officer Friendly couldn't just impound it the first time he saw it!

With the large antinna it looks like a suped up RC car :D

Hee,hee! That's good. What it is not an antenna but a pennant pole wear light flag can mounted to increase visibility to other motorist. In the same way some bicyclist will have a flag on their bike. Since many of these vehicles have very low silohouette, Twitch's car is only about 3'ft tall, the tall mounted flag gives other motorists in larger vehicles a chance of spotting them in traffic, or pedesterians a hope of spotting them as walk through a parking lot. At night the poles usually now by law have a small LED light up there for nighttime visibilty.
In more extreme cases you'll find some of the car clubs bearing large almost sashimono-style flags! Think Japanese motorcycle gangs and you get the picture!
