As a career service member and passionate auto enthusiast, I've had the chance to live both…read moreoverseas and in the US. While stationed in San Antonio, I had some Dinan upgrades done on my BMW 540M Sport, including intake, throttle body, headers, exhaust, and engine/transmission tuning. About a week later, my check engine light came on. I took the car to the local BMW dealership, where it sat for over a month without resolution, despite the fact that I had bought and serviced the car there. One of the techs at the dealership recommended Rhein West, calling them the best in town, if not the entire state of Texas. Initially, I was hesitant, as I typically avoid independent mechanics. However, after having the car towed to Rhein West, they spent just one day troubleshooting, contacting BMWNA, BMW in Europe, and Dinan Engineering in California. Within 24-36 hours, they had my car fully repaired for less than $600. From that point on, I exclusively brought my car to Rhein West until I eventually sold it. Their 2-year/24-month warranty gave me great peace of mind, and every service I received was spot on. If you own a BMW, I can confidently say that Rhein West is the best shop in town, hands down. Their prices are often lower than the dealership, and they truly stand behind their work. These guys are genuine BMW enthusiasts who specialize in BMWs and Minis.
