I had a 2008 C350 that i bought in 2013 with around 95 000 Km , worst nightmare ever,
i decided that for the 1st time i will not take the extend warranty, so after 6-7 days i got the car, i am starting to have acceleration problem,
So i decided to go back to MB laval, they said eveything is working fine... then the next day same problem came back , so i bring back the car to MB laval and again they told me the car is working fine. (bad experience with them)
Now 2nd option come to my mind, i decided to go at MB silverstar in montreal at my charge, found out they don't know what's going on..
So 3rd options, i go to MB West Island, they found out after a minute that the electronic board on the transmission need to be replace, so i ask for an estimated , i was thinking that probably around 4-500$ Problem will be solved..
Oh damn not,, cost is 4 600$ + Taxes to change the board and re-program everything.
i was lucky because i had the 30 days basic warranty on my purchased.
After 6 months i trade the 08 for a C300 2013, new design in & out, more comfortable, run's way better.
So if i was you ,
1st thing , bought an extended warranty
2nd ,you should bough the next generation (2012+).
