2001 Lexus RX POWER TRAIN,WHEELS,UNKNOWN OR OTHER

I BOUGHT A CAR FROM A PRIVATE PARTY/DEALER ONLY TO FIND OUT THAT REPAIRS NEEDED ARE MORE THAN CARS WORTH, THEN I CHECKED CAR FAX TO FIND OUT THAT MILEAGE HAD BEEN TURNED BACK A LOT.. THIS PERSON LISTS 3-4 CARS FOR SALE A WEEK AND I CAN'T FIND ANY ONE THAT WANTS TO HELP. I KNOW I AM STUCK WITH CAR UNFORTUNATELY IT WAS FOR MY HANDICAPPED SON THAT STARTED COLLEGE RECENTLY AND USED ALL HIS SAVINGS FOR CAR. I FOUND THAT THIS PERSON GOES UNDER SEVERAL NAMES AND ONLY LOCATION I HAVE IS WHERE I BOUGHT THE CAR. HIS HOME ADDRESS IS UNKNOWN AT THIS TIME. ATTEMPTS HAVE BEEN MADE TO CONTACT HIM WHERE I BOUGHT THE CAR BUT EVERY THING FAILED AND PERSON IS STILL SELLING CARS TODAY. I FORGOT I WAS SUPPOSE TO BUY A 2003 BUT TURNED OUT A 2001, IF YOU COULD DIRECT ME TO SOMEBODY IN IL. THAT CAN HELP I WOULD APPRECIATE IT. EVERY ONE TELLS ME TO FIND A LAWYER BUT ALL MY SEARCHING CAME UP ZERO PLUS NO HOME ADDRESS AND NO HELP FROM LOCAL LAW. BEEN 2 MONTHS OF DIGGING AND SEARCHING. PLEASE HELP *TR
