Mufflers repair service near Wilmette, IL

I unfortunately have mixed reviews, but I will be honest. I had been a customer for over 6 years prior to the new management. Most every repair (brakes, tune-up or radiator) the service was initially great. Now that the management has merged, the customer service and technical repairs standards has significantly decreased. My last experience before leaving dealt with a radiator replacement in my wife's 2005 vehicle. I ordered and paid for a brand new factory radiator, new hoses and thermostat. About 2 months after the repair I started having the same recurring problem (overheating) before the repair. I approached the manager and from that point on, I could not get the repair issue resolved. I could never get them to provide me the old radiator or resolve the overheating problem that almost caused my engine and transmission to overheat. I pulled the radiator out on my own and noticed that the radiator had never been replaced and they put several containers of "Stop Leak" pellets in. I have not been back to Mufflers for Less since. My advice, make sure you have confidence in the repair facility and always ask to see your old parts that they have replace (photos of the work shown are good pieces of evidence as well).
