CNG roadster thing

[fubar]

I met someone that claims to be buying two of these cars. They are a 3 wheeled , fiberglass bodied, rear VW engine, 3 passenger car that runs on cng. They are supposed to come with a compressor. They claim 70 mpg and 0-60 in 6 seconds. Pretty cool if it is not a scam. http://www.eco-fueler.net/index.php?id=bm1011
