I don't get the point of building replicas. You don't get the power, you don't get the handling, you get somewhat of the look but it doesn't look quite right, it's always a little off and misaligned, like the one in the OP eBay auction, and anyone who knows cars would immediately call shenanigans if they saw one. I'd say it's a poseur thing. If you're gonna make a kit, make it look like no other car, don't be a wannabe F-Car or a Lambo owner! Frankly, one of the worst replicas I've seen was the NSX with the F50 conversion. How much drugs must one take to come up with that? I liked the white NSX that was up for sale here, it had a very original body kit that looked hot and wasn't a replica of any other car! That's mom approved right there!
That's just my opinion though, I prefer originality when it comes to projects. My favorite must be the Civette. That's one of the most bad ass cars I've ever seen.
