Genuine COA.?

[Foxy1305]

I am looking to buy a bit of F1 memorabilia. It's an exhaust manifold from the 2006 season
Renault in its championship winning year. I have found this on sale a £295 from one site but £600 from another. Both say hey are genuine and have a coa. The difference is though I think one says the coa is from Renault and the other is from the seller themselves. Am I smelling a rip off? Is the expensive one real and the other a copy or not off the car stated or am I being too cynical and not trusting a 'half price' deal when I see one

If it looks too good to be true, it usually is.

If the £600 one is the piece with the Renault COA then I'd more than likely go with that one.

Sounds like the other one is a copy... An expensive copy at that.
