So I finally graduated from my Audi A5 cab to Lexus. I will miss being topless to speak .....but I am happy to be spending less money and really love this car. The one regret was I didn't get heated seats. However, I was told there are many aftermarket seat heater products out there. It was absurd to buy the whole package to get heated seats. Frankly, I found it odd that the luxury line would not make that standard. At least a front seat only package. Regardless, does anyone know of a solid aftermarket product and does it have an oem switches that yiu can install?
