I'd suggest trying the Skoda Citigo, SEAT Mii or Volkswagen Up. The cars are mechanically identical and their small size makes them very easy to manoeuvre, they're all cheap to run and spacious for their size.

If you fancy something the same size as your current car, it might be worth having a look at the current SEAT Ibiza or Volkswagen Polo. They both have light controls and can also be specified with an automatic gearbox that means you don't have to worry about operating the gearstick and pressing the clutch pedal. They're also roomy for their size, but are more comfortable than the cars I mentioned earlier.
