W.I. Simonson Inc.

Nick is always doing an outstanding job and listen to costumers needs. He been servicing my car for 4 years now and always take very good care of my car.

All the staff were friendly n customer oriented. I just wish I had a better idea of the actual cost out the door days before the day I agreed to the purchase. They offered to towed by car back home which was close to 170 miles so I can drive my newly purchased car myself.

I really enjoyed the Mercedes Benz dealership! Everything is top-notch: cozy, clean, attentive staff, delicious coffee and tea, pleasant atmosphere, modern interior, fast service, and a true premium experience in every detail. The service left only positive emotions. I really enjoyed the Mercedes dealership!

Sam was the best! Not pushy, friendly, easy to work with and made me feel at ease! He even brought a car up from Calabasas for me to rest drive.

Excellent service, honest approach, great price. Marcus is the best. Repeat customer. Of many years

I asked Derrick Franklin in the service department to take good care of my son when he brought in our CLA250 for a check engine light. Instead, he was handed a repair estimate that was higher than the value of the car. The first line item: thermostat replacement -- quoted at $6,100. To put this in perspective: The part costs about $250. Labor should be 2-3 hours. Coolant about $50. Three independent mechanics all quoted me between $1,000 - $1,500. I left Derrick a voicemail at 1:15pm Friday. He never returned my call. On Saturday, I called again and spoke with the service manager on duty, Kyle Weins. He looked at the estimate and told me the parts department had accidentally "fat-fingered" the coolant at $3,200. He even sent me the screenshot. But when I looked at it, I saw the parts department had entered only 1 gallon. If it truly were a fat-finger error, I would expect to see something like 100 gallons. Kyle admitted it was a manual entry. Translation: someone manually typed in $3,200 for coolant. Even the least experienced parts clerk should not make this kind of "mistake." And here's the kicker: even after removing the bogus $3,200 charge, the estimate was still $3,000 -- triple what's reasonable. Here's the rest of the estimate: Engine mounts, $2,000 Replace sway bar links: $700 Oil change: $370 Fuel induction flush $400 (I don't even know what this is!) A/C Evap core clean and cabin filter: $377 I put all this into ChatGPT, who said that independent shops would charge around half the price. This felt less like an honest mistake and more like an attempt to take advantage of someone young and inexperienced who walked in alone. W.I. Simonson messed with the wrong guy. On Monday, I'm contacting Consumer Affairs.California's Department of Consumer Affairs. They have a bureau specifically for things like this. It's called the California Bureau of Automotive Repair.

Great experience! This is my fifth Mercedes Benz and fourth with WI Simonson. They are always fast, easy and professional.

Came to WI Simonson after buying my last Mercedes from another Mercedes retailer. I?m so happy we came to WI Simonson and met our salesperson John. John was amazing; he was patient, kind, and very attentive. He made our experience very easy. We will definitely be back to WI Simonson and work with John again to get into our next Mercedes.
