For a week now i have notice my c320 01' has been shaking when i hit around 70mph. so anything below that the car runs smooth and anthing above 80mph runs great. A freind suggested that my tires have to be balanced and i did notice that the shaking has been coming from the back wheels. what do u guys think.

It's the alignment of the rear wheels. Take it to the dealer (if it's still under warranty, i forget how many miles it is). If not take to a body shop that has experience with german cars and have them do an alignment on the wheels.

check PSI and do wheel balancing, if not, then try doing a offset measure, ur wheel might have a chance of being "warped"
