We put our last car on EBay. 'We buy any car' offered us £80, but within an hour of the advert going on eBay we had 3 offers of £500, and accepted the first offer.
From putting the advert up to having cash in our pocket was about 2.5 hours. The guys who came to pick it up were very professional and turned up with a flat bed lorry.
The car was a complete non-runner, would go into idle mode pretty much every day, no spare tyre, loads of electrical faults, and to top it off I had filled the tank with Petrol (it's a diesel).
Your car sounds like a perfect 'first car' and at least on EBay you're likely to get closer to what it's actually worth if you have no idea of its value
