Buying a new car isn't a decision to be taken lightly and even if you can't afford a new vehicle and are looking at used models there are still certain aspects you need to check out before parting with your hard-earned money. Look past the shiny exterior and flashy accessories and go armed with a checklist of questions -does it run well, what is the fuel consumption like, and is the engine working to its maximum performance, and if you are not confident in buying a car then you should take it to your local mechanic and get them to give it the once over.
