 Just got out from the dealer again. this is another $1500 spend since last month I spend $4950. this R350 was purchase from the dealer 2012. the mileage was 38000, now the mileage only 53000. this pass 4 years total spend over $20000. average over $1 per mile. I don't know what happens to mercedes. seems like they have no liability to look at and respons for their problems. in fact they made more money from the customer for all their problems.
