I currently run a five-year-old Peugeot 206 SW which has been fine, but I would like to consider changing to something of a similar size that would provide a better (softer) ride, as my wife and I are now fast approaching our 80s and would like more comfort. We also have a J-reg Rover Mini Cooper which certainly lacks comfort but is great fun to drive, so we're not entirely 'over the hill'. I'm assuming I could get near to £4000 in part-exchange and would prefer to chip in not more than £4000 on top.
