I've got a fifth option for you.......Swap Zed's with me!
Here's 4 good reasons why............
1) You'd still get to drive a Zed! (still oem sadly!)
2) My 06 GT only has 41.5k on the clock so another years mileage wont make much difference to the value!
3) I only live 15mins from you (Cathcart!) so you could come and visit your old Zed whenever you wanted!
4) You could relax safe in the knowledge that a fellow Forum member will look after your old Zed!
....That is, as long as the value of your Zed with all it's Mod's is about the same as mine?!? ie £12k ish!
Please say yes!
