Black 2012 Buick Verano. Tan inside seats. Just changed spark plugs. Camshaft intake and exhaust sensor. Kelly blue book has the value at 5,600. In the condition it is I’m only asking for 4,800 (willing to negotiable) to fix any issue with car and for the tow it’ll need to be towed. Yes it drives but it starting to shake when idle and stop when at lights. The problem is just changing one piece but I have no patience or time to find out which piece. Any mechanic should be able to figure it out in no time. I already replaced the plugs and sensors so that’s not the issue. It’s either something with the gas or I’m not sure. A/C work the car runs still it’s just the jerking when idle and stopping when at lights. Once that fixed the car runs normal. Clean Title. Possible the only issue is the CrankShaft which I haven’t changed yet.
