WHY IS IT THAT MERCURY SABLE HAS HIGHER RATINGS THAN IT`S COUSIN THE FORD TAURUS?

[RU4ME]

I HAVE A 2005 FORD TAURUS WHICH HAS BEEN A GOOD CAR FOR ME SO FAR, I GOT I BACK IN 2006. BUT LIVING AND WORKING IN THE CITY HAS BEEN A PAIN FOR ME AND MY CAR. THE WHEEL BEARING IS OFF, THEY SAY I NEED NEW SHOCKS AND STRUNTS, AND NOW THE TRANSMISSION NEEDS TO BE REPLACED.I FOUND OUT AFTER BUYING THE CAR, I LOOKED IT UP ON CAR FAX AND EVENTHOUGH SHE IS A 2005 AND I GOT HER IN 2006, THE CAR CAME OUT IN 2004.SO SHE IS 6 YEARS OLD.NOW BEFORE I HAD BROUGHT THE TAURUS, I WANTED A MERCURY SABLE FROM THE BEGINNING, BUT THE FORD DEALERSHIP GAVE ME A BETTER OFFER THAN THE MERCURY DEALER DID. SO I ENDED UP WITH THE TAURUS INSTEAD OF THE SABLE. I WAS THINKING IS STEAD OF PUTTING ALL OF THIS MONEY INTO THIS CAR, I WOULD GO AND GET A 2004-2006 MERCURY SABLE INSTEAD, FULLY LOADED, LIKE WITH LEATHER INTERIOR,WOOD GRAIN, SUNROOF ETC. I HAVE READ CONSUMER REVIEWS ON THE SABLE AND THEY ARE BETTER THAN THE TAURUS REVIEWS. BUT I AM CONFUSED BECAUSE THEY ARE THE SAME CAR JUST ONE IS IN A TUX AND THE OTHER IS NOT.I`VE EVEN LOOKED ON EDMUND'S.COM,MSM.COM CONSUMER GUIDE.COM AND ALL SAY THAT THE SABLE IS A GOOD CAR FOR THE MONEY, BUT WHY NOT THE TAURUS?NOW AS MUCH AS I WOULD LOVE TO BUY THE 2010 TAURUS WHICH LOOKS SHARP TO ME, I AM NOT TRYING TO SPEND A LOT OF MONEY RIGHT NOW. I KNOW THAT PEOPLE THINK THAT FORD PRODUCTS ARE A PIECE OF JUNK, BUT ALL OF MY FORDS HAVE BEEN BETTER THAN SOME OF MY FOREIGN CARS THAT I HAVE IN THE PAST.RIGHT NOW I HAVE A SECOND CAR AND IT IS A 2000 FORD FOCUS AND SHE HAS 151,000 MILES ON HER, AND THE MECHANICS ALL TELL ME THAT HER ENGINE IS IN EXCELLENT CONDITION, THE PROBLEM I HAVE WITH IT, IS WHEN I GET ON THE HIGHWAY IT HAS NO SPEED, EVEN MY TAURUS, WHICH IS A LITTLE DULL, PICKS UP VERY WELL AT HIGH SPEEDS.
