As cars get older, their parts need to be replaced--if they can't be rebuilt. When I took in my 2010 Malibu to Big Jim's Auto this time, the mechanics purchased and installed several new parts. But they also informed me of the warranties that came with the parts. Big Jim's does this. They get the warranties and keep track of them for me. This can result in savings down the road. When I visit Big Jim's next, my car will show 356,000 miles on the odometer.
