You have posted this in the GE section of the Jazz forums, but at that date, if it really is a CVT, it must be the older GD model. The GE range didn't have CVT until 2011. The other possiblity is that you are looking at an i-shift automatic GE, not a CVT. If you like the i-Shift fine, I couldn't stand it.
Assuming it is a GD CVT, my initial reaction is that that the price is too high, even allowing for Main Dealer etc.
I bought a 58 plate Jazz GD 1.4 CVT7 first reg 01/09/2008, mileage 29,000, last July from a Honda Main Dealer with Honda warranty for one year, service and MOT. I paid £6,945 which I thought was at the upper extreme.
So, eight months later than me you are paying only a little less than me for a six month older copy of the same car.
This model is not rare so I think you should be able to do better.
Only caveat to what I have said is that I am not sure what a "Crown" Honda is (dealer's name?), and that mine is an SE spec. I think you are saying yours in an SR spec, which isn't mentioned in the brochure I have. Maybe SR spec is worth a lot more? EDIT I see yours is an SE as well.
You might want to try and repost in the GD section, or maybe the mods will do it for you.
FWIW the Jazz I am talking about above is my wife's....I have a Jazz GE which I like a LOT more!
