When I leased my new Challenger, I opted for the 3 year/36k mile maintenance service plan. It cost me $1,150 but I have 60 days to cancel for full refund. Reason I got it is so I have proof for the leasing company when I return the car that I upkept the car and there's no reptuable mechanic in town that works on Dodge/American cars. My question is: can I use Oil Changers or Jiffy Lube for the 5000 mile oil+filter changes and do the 15,000 and 30,000 mile intervals at an actual shop? Would that be sufficient for the leasing company that I took care of all maintenance?
