Salt Lake City Service Options?

I made the mistake of choosing M & M in SLC to try to sort out some electrical issues--TPMS sensor and Airbag warning sensor in my 2010 Maserati Granturismo S. At $220/hr it came to $1260 and when I drove away, the TPMS issue came back...I chose them due to a slightly lower rate than the dealership at $290/hr.

Other than the Ferrari/Maserati service (Ken Garff dealerships) are there any shops in the area worth looking into? I would not recommend M & M for any vehicle work based on my experience there. They texted me asking for feedback on their service afterwards, and I haven't heard from them since...

 

Thank you! Will do.
