OK, so that means that mine is worth about £17 4s 6d. Great.
Looks lovely.
Why not buy this as your new daily workhorse? It's well below your budget, leaving plenty to pay for petrol. Run it for a year or so, then sell for (possibly) not much less than you'd pay for it now.
Hmmm. Food for thought.
On second thoughts, the Sat Nav is shocking. I'm out!
