I'd say that was a genuine Ed30 myself. It has the Ed30 badge over the glove box too.
Was just going to post surely the BYD code (which I think is Ed30 only) will confirm for sure.
But the garage has given that info now.
And centre armrest was an option on these in 2007..as I spec'd one.
About £115 if I recall it was. My cheapest of the 3x options I put on it.
Roof and Xenons weren't that cheap.
Good luck with the search anyhow.
