Talking about old Volvos, funnily enough, I'm about to do the same thing.
I've got a 32,000 mile old Volvo C70 convertible, that I've owned since new, which according to Glass' guide should be worth about £13.5K retail.
Now that I work at home I've only done 2.5K miles in the last year, so it's an expensive lump of metal to have sitting around doing the best part of FA.
It's especially expensive to have a flash convertible sitting around, since I've just learned this week that Mrs Jools (who is in hospital as I write this) has definitely developed Multiple Sclerosis and may not be able to work anymore (well, not until she can walk anyhow).
It's due for it's MOT and Tax at the end of this month, so I will get that done then take Mrs Jools on a jaunt to Devon in early April, 'cos her best friend has just moved to a place near Barnstaple. Hopefully the sun will be out, we can get the top down and use the journey as the last hurrah for the car. After that I'll be selling it for about a couple of grand below Glass' valuation for a quick sale.
It's a lovely car, but being a convertible there's not enough boot space for a wheelchair
It'll have to go to make way for one of those big old Volvo estates - you know...the ones that bikers hate
So, watch this space in a month's time if you fancy a bargain convertible
