Dealt with Andrei to perform a PPI "be my eyes & ears" of a 2003 BMW M3 in the Bay Area as I was based in Los Angeles. I never met Andrei, but from speaking with Andrei on the phone, he seemed to have the technical knowledge with BMW's. I hired EDGE Motorworks to perform the PPI results and was very impressed with the PPI report. The report was very thorough, detailed and identified a lot of issues that I was able to see in person and when I had the M3 back home. I would use EDGE Motorworks again and recommend their work!
