As you can see, everyone here is very protective of our little niche industry... and quite frankly probably tired of seeing people taken from their hard earned money. I am not saying that @SoCalSpeedster falls into that scammer category at all, BUT I also don't believe that the failed companies set out to scam people (except one that is clearly a ponzi).
I think where most take issue is that you came on and started by calling yourself a "leading manufacturer" for over 15 years... I know many here had an issue with the new Vintage in AZ staking claim to the old Vintage's 3300+ car and 30+ year history, despite no one in the new building having build cars for very long. In your case you're laying "manufacturer" claim because you acquired a company that sold used cars, in some cases "restoring" those used cars, swapping engines, interiors, whatever. In later years they bought a few kits from the various manufacturers and private labeled them as their own. Lots do this, but a manufacturer does not make... Those of us that have been around for many years can look at the spyder chassis pictures posted, know exactly what they were copied from and who is making them in Mexico currently. Same goes for the speedsters, there are several "tells" in fender shape, headlight placement, bumper shape, to name a few. I am one of the guys who feel there is a place in this industry for many companies, entry level to top tier, and only time will put you in your proper seat. So that said, I wish you good luck.
Now... where I have personal issue is far deeper than that and it probably boils down to "you don't know what you don't know". Sir, I count no less than 8 separate times on your website that could potentially get you shut down and bring additional (unwanted) attention to our little industry. As a savy businessman you can do some research and figure out what these are, I'm not here to teach and those of us that have truly been here for a LONG time took our licks and have since healed our wounds.
In summation, I truly do wish you good luck in your venture, its a long and expensive uphill battle, especially if you don't figure some things out pretty quickly... time will tell.
