Newbie Post... SPF's (general)

[Scoot]

All...
How goes it? Not quite sure where to start, but as the subject line states- I'm a newbie to the Cobra realm. Being new to this forum, I have MANY questions... many more than time allows.
For starters... Superformance replica's = "SPF" (?). The reason for the inquiry- this seems to be the company I'm leaning towards purchasing from. To my surprise, however, there are quite a few replica companies as seen on various threads throughout this site.
I've been researching Cobra Replica's for a 'near future' purchase and want to make sure I do my homework FIRST! I plan on dropping $40 - $50 for a turn-key vehicle (delivered to my garage). So, I figured I need to go to the source, hence this post.

Can anyone direct me to a specific forum, or thread, that details SPF specific's? Most of my questions are general in nature- such as: diff's between 'early' model vs. 'late' model, common upgrades/modifications (excluding engine/drivetrain), cautions or problems, titling/registration issues, etc...?

I know these answers could be lengthy, so any direction would be appreciated . Also, I'm open to critic's... any other manufacturer recommendations (?)... and if so - why?
Thanks much.
