You probably know more than me about whats selling and what isn't, so Im afraid I don't have an opinion on that.
You buy what you like don't you. I don't care for fitted Sat Navs (I have my own as I tow a caravan so small roads are no good for me), The latest sound system or Tvs etc etc. So long as I have real leather, and a colour I like, Im happy. The more gadgets the more to go wrong, dont they say
