bad motor mounts can cause the vibration around 60-80 mph? ( after tire balancing)

hi, guys.

Just got the 2004 passat V6 a mouth. there are so many problems...when I got the car, I found my car has a vibration around 60-80mph. (pretty strongly shaking, and I can even feel the pulsation on the gas pedal. the whole car is sharking!! ) I was told the control arms for both side was bad, and the cv axles. so I replaced them with aftermarket. But the vibration still there. then I do the whole 4 tires re-balancing. But the problem still there. after doing these, the mechanic also told me my engine mounts for both side was worn and need to be replace. now, it is a dilemma, should I really invest it onto this car. I don't wanna put the money in and got nothing( problem still there like before)....


if I really need to replace it, I may just replace it with those aftermarket. $50 for each one. I don't have that much budget...

I got few symptom that I felt it is motor mount but I am not sure:

1. when starting from a full stop, there is a clunk. ( hit the gas pedal strongly)
2. there is a click sound coming with the clunk.
3.the vibration, for me, come from the driver side.

help you guys can help me.
