Engine repair service near La Grange Park, IL

I brought my car in for a diagnostic and they gave me over a quote for over $3,000 in repairs. I took it down the street for a 2nd opinion and half the things they said were wrong was a lie. Had my car repaired where I got thr and opinion for less than 1k. It's been 6 months and not a single problem. A dealership and repair shop run by conmen. Color me surprised (NOT)

Jamal(Store manager) is one the biggest crookes in the automotive industry who takes advantage of unknowing customers .Not only is he very unprofessional but also marking up prices over 5 times what they cost.My mom went there and was charged $4000 dollars for under $2000 in work (had a dealership and 2 independent shops verify this by a second opinion and quote ).Not only that but Jamal charged for parts that were not even changed .When he was confronted on his shady borderline criminal actions he became very belligerent and rude !! Escalated to corporate (bill Gallagher) who I was assured would return the call that day and he took a week to just call back !!with no solution to these obvious issues!! DO NOT I REPEAT DO NOT DO BUSINESS WITH THIS COMPANY !!!
