06 BMW 750Li FIXER UPER RUNS AND DRIVES

OWNER INFO:HELLO!......IM JOHN IM AM NO CAR SALESMAN SO BARE WITH ME. I AM THE SECOND OWNER OF THIS BEAUTIFUL CAR, MYSELF HAVE KEPT THIS AND ALL MY CARS CLEAN AS I CAN WHEN SOMETHING GO'S WRONG IM COMPELLED TO REPLACE IT.
WHERE PURCHASED:I GOT THIS CAR FROM "STATEWIDE AUTO SALE" A CAR LOT IN SUNLAND, A CALIFORNIA. I LOVED THIS CAR FROM THE DAY I GOT IT ALL THE WAY UNTIL NOWIT TRULY IS THE "ULTIMATE DRIVING MACHINE". I WAS TOLD THAT AT AROUND 90K THE CAR LIKE ALL THESE CARS WOULD START TROUBLE AND SURE ENOUGH AROUND 93K ONE THING AFTER ANOTHER THINGS NEEDED REPLACING, UT HERES THE GOOD NEW IVE SPENT ALMOST THE COST OF THE CAR REPLACING EVERYTHING THAT WENT BAD ON IT I LOVED THE CAR THAT MUCH LOL. BUT NOW THAT I HAVE A NEW LOVE IT'S IS TIME TO SELL.
WHATS WRONG WITH IT:AS OF RIGHT NOW IT NEEDS A CATALYTIC CONVERTER OR IT WONT PASS SMOG (THE REASON I STOPPED DRIVING IT)
THE TRANS SKIPS AROUND 1K-2K RPM DRIVES GREAT ON ANY RPM HIGHERI WAS TOLD IT COULD BE A NUMBER OF THINGS CAUSING THAT PROBLEM COSTING FROM $300-$2,000
SMALL OIL LEAK FROM A LOWER HOSE DOESNT EFFECT THE DRIVING JUST LEAVES A STAIN WHERE EVER I PARK IT FOR LONG PERIODS OF TIME.
I HAVE, ND WILL DO MY BEST TO HONESTLY REFLECT THE CARS CONDITION IF I MISS ANYTHING I WILL KEEP UPDATING THIS AND OR ANSWER ANY QUESTIONS AT ANYTIME 24/7 I HAVE PRICE THE CAR WITH A REPAIR WORSE CASE SCENARIO FOR COST TO FIX TAKEN OUT.
