1981 FORD THUNDERBIRD, RARE HARD TO FIND CLASSIC CAR

INSPECTED UNTIL 8/18. NEW BRAKES & ROTORS. FULL TUNE-UP.THIS CAR STARTS,SHIFTS AND RUNS BUT IT NEEDS SOMETHING FIXED AND I'M NOT SURE WHAT IT IS. IT CAN BE A CHEAP FIX BUT I RAN OUT OF MONEY TO FIX WHATEVER THE PROBLEM IS. WHEN MY MECHANIC WAS DOING ALL THAT OTHER WORK I JUST MENTIONED HE SAID IT WAS A GOOD CAR AND HE CONFIRMED THAT THE MILES WERE ORIGINAL. IT HAS UNDER 75,000 MILES, (SEE PIC). EVERYTHING IS ORIGINAL RIGHT DOWN TO THE RADIO. NEEDS A HEADLINER AND HAS VERY LITTLE RUST (SEE PICS). A CAR CLASSIC COLLECTORS DREAM. IF YOU LOVE CLASSIC CARS AND HAVE A LITTLE EXTRA MONEY TO FIX THIS CAR IT'S WORTH YOUR DIME AND TIME. TIRES ARE 90% NEW. INTERIOR IS IN GREAT SHAPE, NO TORN/RIPPED SEATS AND EVERYTHING WORKS. GREAT HEAT BUT NO A.C. FOR THIS PARTICULAR MODEL.THE PROBLEM SEEMS TO BE A COMPRESSION ISSUE. POSSIBLE INTAKE MANIFOLD. BUT THEN AGAIN I'M FAR FROM A MECHANIC. WHATEVER THE ISSUE IS THE CAR STILL IS IN GREAT SHAPE AND A GEM OF A CAR!! CAR COMES WITH A HALF TANK OF GAS!
