I noticed a slight increase in vibration with the ipd mount just after installation, but I got used to it quickly. Now I don't notice it at all. Some posters have noticed no change and others have removed the urethane mount because they felt a lot more vibration. I would recommend that you try it for $26 and install yourself and if you don't like it, have the OEM one installed. I have heard that installation of the OEM mount requires a press of some sort to press the new one into place.

I am not a big believer in 60K or 30K services because most of the items you can do yourself and save a lot of money. These cars are very easy to work on and I think doing your own maintenance makes it easier to diagnose problems. Get a Haynes manual and read the maintenance section. It walks you through what needs to be done. Also check out bay 13 on volvospeed.com for instructions. Save your repair money for the things you can't do yourself. I had my mechanic do the timing belt and it cost around $225 and included replacement of the serpentine belt. Prices will vary greatly based on where you live. Good luck.
