there are LOADS of kit car companies!!
have you even looked at the kit car mags?
do you know what type of kit your after? lotus 7 rep, cobra, etc, etc.
do you know what donor vehicle you will need? sierra, jag, metro, etc.
i suggest you start reading into it all first and visit at the very least 1 kit car show and speak to owners and the companies first to decide what you want otherwise you WILL make a very big mistake costing you thousands!
