RE: honda accord motor mounts
Yeah, $600 sounds way too high. I got motor mounts replaced on another car that I had (not Honda) but it was around $300 plus other things I believe I got done. I once replaced (isolation mount) (or dog bone mount) on a car as well and that was around $50. But, don't do that job for $600. If you have no problems you are fine!
