It is quite a catalouge and good prices, any reviews?

Between threads here and at zcar.com, the consensus I have seen is to stay far away.

What ever you do, do not use them, I made the mistake one time and took me over six months of repeated emailing to finally get my order which Showcar had shipped from another company! Trust me, you may never get what you order if you choose them.

Thanks guys.

The guy that runs that business was at a local car show here a couple of Summers back.  Based on my impression of how he presented himself, what he was driving, and his general demeanor when chatting, I would say that giving him your money and getting a quality product in exchange is very very unlikely.  

This was a pretty epic read as well though:  https://www.complaintsboard.com/complaints/showcars-fiberglass-steel-bodyparts-unlimited-c10197.html

For more insights, try a Google street view of his business address

I think he's just a re-seller.  And not a very good one, it seems.
