I actually bought this car from Carmax (I know! yuck!) after I investigated and talked to the original owner and the dealer who did the service. The motor mounts were changed just before I bought it. The original owner said they would probably last another 30K. Right now, it has absolutely no vibration whatsoever, but I am a little worried with its history of 2 replacements already! (once at 30K and again at approximately 70K)
