To be fair Jazz999, if you have a budget of circa £20k, you have a vast array of options available to you. Honda HRV and CRV with low mileages at 1 or 2 yrs old. The option of a brand new car with a 7year warranty like a Kia Ceed, or the Kona and some change left over!
Fancy something a bit more 'prestige'? How about a year old Mercedes A Class at your budget, nearly new BMW 2 series Active Tourer or Lexus CT200h.
£15k puts you in a low mileage Auris Hybrid that is a safe eco friendly bet that will last for ever.
I would echo what
