THIS CAR SHOULD QUALIFY AS A LEMON. WE SPENT OVER $65K ON IT NEW IN JANUARY OF 2009 AND IT HAS EASILY COSTS US $65K TO KEEP IT RUNNING SINCE. SOMETHING SIGNIFICANT BREAKS ON IT EVERY 60 DAYS SINCE OWNING IT. THE TURBO WENT OUT MOST RECENTLY AFTER A BAD OIL SEAL LET OIL INTO IT. $6500! THE CAR MAY HAVE SADLY BEEN CURSED SINCE DAY ONE. OUR SALES PERSON AT MERCEDES BENZ OF SF DIED RIGHT AFTER WE BOUGHT IT. THINGS STARTED TO BREAK IMMEDIATELY AFTER. PEOPLE RAN INTO IT, ETC. IT HAS BEEN THE WORST CAR OWNER EXPERIENCE IN MY LIFE. *TR
