As per the title really!! I'm about to book mine in for it's 36k service and thought I'd ask if they had a courtesy car with the new D5 available to have a go in it.
That seems like a decent improvement in BHP, although not a massive one. How much lower are the emissions? And does the economy improve, as the d5 and 2.4D arent exactly in BMW league when it comes to diesel engine technology and economy.
