That's cool. I'd try and talk him down, unless he's selling it for a good deal. The cocker market is SO dead right now, that you should be able to pick it up for cheep.
Don't let him try and tell you it's a lot older than it is, the serial number is low since it's a mini.
Good time to buy it then! I hope you get a good deal. The CCM kits are quite nice.
