It did NOT happen every time I stopped. I have drive vehicles with the compressor kick, but I am pretty sure that what I heard/felt was more intense than what the AC could do. So I am starting to think it might actually be mode switch or transmission fluid level / service.

FYI - This is a VX I am looking to purchase, and noticed the problem during a short test drive. I think the combination of louder exhaust, rough road, and the "clunk" left me with the feeling that the ride was somewhat more rugged than the other VX's I have driven. I'm trying to decide if all of this put together is telling me to stay away from this VX, despite it's color and low miles.

Thanks for all of your tips, guys!
