I have been going to Auto Plus in Lombard (oil changes and routine maintenance) for a few years now. On my most recent visit they noticed an oil leak from underneath and informed me that it was still covered under my new car waranty of 3 yrs/ 36000. My car had 35,000 miles, so I brought it in to VW the next day and they saw the same thing, fixed it free of charge.
Auto Plus and their staff, saved me hundreds of dollars by pointing this out. I will definately be bringing my cars back to Auto Plus in the future. They are honest, and do a very complete job of inspecting your vehicle.
