Their insistence that this is normal and/or fixed makes no sense. The shop foreman repeatedly stated he can reproduce the issue and agrees it's a problem. Otherwise they wouldn't have tried all the previous part replacements. If the thumps are not only still there, but are now worse, stick to your guns for a buy-back.
Have the regional rep come out for a test drive with you and the foreman and see if he'd put up with it in his daily driver.
Does the car feel any different when the thumps occur (vibration, etc.)? Have they ever looked at it replaced the wheel bearings?
