My X5 needs AdBlue.
It takes 5-10 minutes to top up and the stuff is easily obtainable from your usual motor factors.
Mine needs a top up around every 7-8000 miles, it's no worse than having to top up oil or coolant or windscreen washer fluid or air in the tyres.
Big fuss about nothing in my opinion

If I recall correctly, my last refill took about 5 litres, so £20 is enough for about 15,000 miles' worth.
I'd be more worried about an extra 1p on the price of fuel if I were you!!!
