Favour request: Trade in valution

[JonnyO]

I know its a bit cheeky but Id very much appreciate it if one of the traders here could give me an idea on the value of my car in trade? Basically so I know what cash to move around so I can pay the dealer on the day.
I'm looking to buy an VW Eos at about £8000 (want a convertible ready for summer).
My car is a Fiat 500 TwinAir Plus. 11 plate with 23,000 miles on it. In excellent condition in midnight indigo blue. Full dealer service history and with full leather interior and black roof as options. Not yet been MOT'd as not due its first until June.

Not really a 'proper' valuation but here's CAP (assuming 2011/11, 20,000 miles and not a Dualogic, whatever that is)

Retail: £8,595
Clean: £7,350
Average: £6,875

Thanks. That's good information and means I can get the money ready to do a deal straight away if I see a car I like. A little better than I expected to be honest!
BTW, the dualogic is the automated manual gearbox.

I always use WBAC to get an idea of trade value - normally within a few hundred (on the provision its a mainstream car)
