A friend of mine is a British-Hungarian dual citizen, who spends most of his time in Budapest driving a 1997 4.0 Range Rover. It's a crowded capital, and a gallon of petrol is $6.81 around here. Still, there's a good reason for his choice.
The British used car market is a weird one. You can get great bargains all around, but when it comes to insurance, things can get complicated. It can cost way more than what the car is worth in the first few years, especially if you're young and live in London. On top of that, the demand for younger sedans keeps their prices higher (at around $4,800 for a good one), and you can't expect too much luxury when all you have to trade in are portraits of the Queen.
