Hello Everyone, New to Ferrari, long time Porsche owner. I just picked up a '98 550. Love the car. I now see what the fuss is all about when I get behind the wheel of my own Ferrari. One question, does anyone know what AC compressors work best with Ferraris? I've been through two already and still no AC. Is my only option buying an OEM compressor? Any advice would be greatly appreciated. Thanks, Phil
