I have a real coolant overflow tank to go with it. the reason it is so expensive is because everything is hand built. ill try and get some pics of the underside too. it has a full skid plate. this car was built professionally. the dash is actually one of my favorite pieces. it is a hand made carbon fiber piece that was built from taking two integra dashes and putting the together. it was then finished in suede. for suspension it has fully adjustable DMS suspension. i am working a list of everything done to this car. ill post it when its done. i dont have any videos but i will try and make some.
