Hi - thats brilliant news!! congratulations!!!
To get Rays, there are a couple of methods...
Firstly, post up a wanted add on the site - there are always owners changing their wheels that may have a set they would be willing to sell.
Also, keep an eye on ebay - thats where I got a set from for the last car. They have gone for up to very near the £1k price in the past, but should now be considerably lower.
They wont fit in a Z if you go to pick them up though, so you'll need another vehicle to transport them in.
There is a meet in the Lake district on Sunday next weekend, you could even come along and show your new car off and meet some of us!
You're going to ache from the smiles after picking her up and getting through your first tank on Saturday
