Wait abit longer and get what you really want in my opinion, even of it means spending more. I bought mine from a DVLA auction for around £3000 and I have seen a similar one sell for £9000 since then, yet I wouldnt sell mine in a million years as it literally is as close as I can get and requires no spacing, but as I say it all comes as a price, but at the same time an investment, one of the best purchases I have made.
Excuse its on my old car, havent transferred it to the Z yet, still waiting on the document to come.
