They are one of the most unique cars on the road imo..I saw one a few years back, I'd say anyone who has owned a k11 has probably thought about getting one of these at some point
The one in question was chopping rx3s, rx7s and your standard big jap cars on the street runs that used to frequent western sydney.
The fella was in his 30s and had upgrades the charger and turbo amongst other work and only have one seat in it.. he even looked anorexic which takes weight reduction to the next level
Going off what he said you can get a lot for your dollar with a better turbo, charger of one of the toyotas and a remapping of the ecu (as well as your standard breathing bits) but he did mention it could be tempremental
