BMW X4

You pay a premium for the X4 over its close relative, the X3. That said, compare the X4 to its most obvious rival, the GLC Coupe, and the asking price is broadly similar depending on exactly which model you consider. Running costs promise to be reasonable by SUV standards, especially if you opt for the 20d. Its fuel economy and emissions figures better those of the equivalent Mercedes-Benz, so it will cost less to fuel and company car drivers will pay less tax. If you want more performance, the 30d still has reasonable running costs. However, the top-of-the-range M Sport models will cost a lot more to fuel. Resale values should be strong.
