WELL FOR STARTERS THE CAR HAS 131,000 MILES ON IT AND CLEAN INTERIOR. BUT....THE DRIVERS SIDE POWER SEAT INCLINE DOESN'T WORK, THE BLEND BOX OR AN ACTUATOR IS BAD, THE CRUISE CONTROL DOESN'T WORK, AND THE AC COMPRESSOR IS LOCKED UP. BUT.... THE WORST PART IS THE OIL LEAK COMING FROM THE FRONT VALVE COVER. IT IS SPILLING OUT ON MY EXHAUST MANIFOLD AND SMOKES BADLY. I JUST READ GM HAS A RECALL ON ALL THE L67 3.8L SUPERCHARGED MOTORS IN GRAND PRIX AND REGALS AMONGST OTHER MODELS WITH THE 3.8L BUT NOT THE RIVIERAS. CAN THE RIV GET SOME LOVE TOO. I LIKE THE CAR BUT ALL THESE PROBLEMS AND A HIGHWAY SHUDDER AT 65-73.....👎👎😢😢👎👎👎😩😩😩😩😩
