Thanks. But what are the pros/cons of the Active Power Cars GT40 when compared to RCR, CAV, ERA, Superformance, etc
how/what different is this from the original?
how is the build quality?
how valuable are these compared to the other replicas? how valuable are these on the used market?
Welcome to GT40's but please go back and re-read the sign up stuff for the forum. There's a line in there where you agree to use your real name on the screen. Odds are that Beemerboy is not your real name. The Mods here are pretty sharp on this so I'll save them the typing.
With just some basic perusal, you can very quickly get a good assessment of the differences between the manufacturers you list and how they differ from Active Power and the original. As to whether they are pros or cons is a personal assessment: do you want originality, amenities, etc... Some people have very different ideas of what they want and yours will likely be different than others.
Build quality is highly variable. Build components can be cataloged and verified, build quality isn't something you can get a handle on through that video. I built my own RCR and I am an amateur. I have had to redo things along the way and there are still things to redo, but I can also say that I have over 6,000 miles on mine, and only once did not come back under my own power. Find out who built it, see what else they have built. Did they sell any others? Talk to the current owners. I would be hard pressed to believe anything the dealer has to say.
There are Active Power builds on the board. Look through them. PM the member. Go visit them.
If you're in the Portland, OR area, you'd be welcome to check out mine, and I'd imagine the other one ~10 min away too (turn-key minus build).
Values are too finicky to hypothesize.
