I love the 240, I’ve had about a dozen with two in my driveway now but A/C is required here in Miami so I’ve been through this on almost every one…. I can’t think of anything harder to get to than a leaking A/C cabin evaporator, which always seems to be the culprit in my case. It seldom can be repaired, buying a junk one is a no no and even the aftermarket ones are pricey. Other than that, keep it up and it’s a great car.
