Why on earth wouldn't your car make it?
I suspect the £310 Seat Toledo I bought recently would make it and make it round a few times, quite happily.
It doesn't have to be anything fandango, it's more important that it's just continent fluids-wise and nothing's about to die.
Just check it over carefully, replace anything that is towards the end of it's life and get in the car with a wallet stuffed full of Euros (more expensive than last year).
Given that all you have out there is third party cover at the most, there's a strong argument for taking a cheap, but well-maintained car out there - if you bin it, you walk away from it without a complete wallet-massacre.
