GMC Sierra 1978 Used Manual Gasoline Peace be upon you.. GMC model 78, 454 engine. It has been parked for more than 10 years, it was working. Very, very active. I don't know about it currently. The registration has expired for more than 15 years. I expect it needs 2000 riyals to renew. Chassis and interior are guaranteed. It has been offered outside the site for 25. And the sale is easy, God willing. Communication via the site only Due to the large number of calls and disturbance..
