Useful that someone has mentioned tax. £140 for a Corsa seems ridiculous in my opinion. My 1.6 Mondeo was £30 a year. My Mums' 1.2 Fiat 500 is £30 a year, and my 2.0 litre Mazda 3 is, wait for it, £30 a year. If emissions are important to you, then there's plenty of vehicles out there with 'allegedly' low emissions that will cost you bugger all to tax, and over the years is a significant saving when factoring in repairs down the line, or better still, can help increase your budget for a better spec/newer car.
