Default Seat Vibration.

I took my car to a mechanic the other day to get the spark plugs change. Then I notice when I turn my car on my seats starts to vibrate when in idle. Is this normal cuz the mechanic says this is normal and that every car vibrates just a little. I read some where it could be the mounts but someone on here told me they not because it doesn't shake my seats just vibrates if I seat there I can feel the seats vibrating on and off its not crazy bad vibrate. It's a minor vibration. I was hoping for no vibration what so ever like sitting in on my leather couch in my living room. Mine is a old model 2002. Any advice would be great!

Yes, I'd aggre with Barcadi, but before spending more money please check this first:

Check for the basics like a misfire. After a service your mechanic may have broken the wiring to a coilpack, or more likely a marginally effective coilpack gave up the ghost after the normal handling involved in swopping in a set of spark plugs.

So.
Check for misfire first and if that confirmed as fine, then look for a torn engine mount as it's also a well known issue with these cars.
