The CT200 is a great car, is really comfortable and will do 55+ mpg. Make sure you are happy with the way the CVT gearbox works it is not like other cars, I am now used to the way it works and find it no problem. There is always lots of advice on the internet about what can go wrong with a car but it really does depend on the individual car. A thorough inspection of both the car and paperwork is a good idea, you could get someone like the AA to do an inspection for you for a reasonable charge.
