Low mileage 460 Si. What's it worth?

[Jaguar steve]

Mums finally giving up driving. Her weapon of choice for the last 23 years and bought new has been a 1.7 auto 460Si. It's done just 46000 miles, been main dealer serviced every year and got good - almost new - tyres. MOT to November and it's had the timing belt done recently. Body and paint is good apart from a couple of minor dinks, interior is as new and everything works.

Any love for the 460 in Volvoworld and any idea what to ask for it or where to sell it?

Cheers Chaps
