Aerial

Radio reception in car has been rubbish recently. I found the aerial was broken and went to Nissan dealer for a new one.
Cost was nearly £40 and had to be ordered. However, the nice man behind the counter got a posh one with teh wirly bit on that is supposed to be fo a big 4x4 - which was only £20 and fits perfectly

Someone in an office somewhere knows why this makes sence!!!
