I want to buy a larger sedan such as a Toyota Camry, Mazda 6 etc. with a budget of around $15,000 - $18,000. Not locked into either of these brands just that type of car. What would you recommend and what should I look out for (eg. car approaching major servicing etc.)?
When buying a used car no matter the make or model the most important things are condition and service history. Buy the best car you can afford within your budget, one with a full and creditable service history. The Toyota Camry and Mazda6 are good reliable vehicles.
