A used car with great A/C

I currently own a 2003 Mercedes CLK320, but it doesn't get the job done when it comes to cabin cooling, even though the system was just recharged and the system holds the refrigerant.Where I live, the temperature rises up to 47 degrees Celsius, so it takes my car 15 minutes to cool down after staying under the sun for a good period of time and it doesn't get that cool tbh.I'm on the verge of selling my car and buying another used car for the sole reason that it won't cut it for this summer, any used cars recommendations whose A/C's blast cold air no matter how hot or humid it is outside? The car should be reliable too. Please write down the make and model, not just the make (GM for example) but the model itself tooAround $6k is my budget via /r/cars http://ift.tt/2swHuCp
