BEST AUTO DEALER IN ALAMEDA & ALL OF BAY AREA!
BEST AUTO DEALER IN ALAMEDA & ALL OF BAY AREA! My daughter recently purchased her first car & Alex made the experience so seamless! She was referred to Diamond Auto Sales by two friends who had bought their cars from Alex. They highly recommended him. I usually dread the car buying process but Alex completely changed my views. He was honest, friendly, thoughtful, funny, and very knowledgable. You can tell he takes pride in each car he has available. He didn't pressure my daughter at all and once she decided to buy it, everything went so smooth. I highly recommend Alex and Diamond Auto Sales! Thank you so much Alex! I will definetly be back when my son gets his license and when I finally decide to treat myself to a new car. In the meantime I will be recommending them to all my friends & family. Thank you Alex and team! We are so grateful.
Kompressor Kicks on all accounts
No better value for your money on the MB SLK Kompressor! Even with a lot of mileage, if you maintain the maintenance aspect of the vehicle you will not be disappointed in it's performance. I've loved this car from the moment I drove it. Parting will be sweet sorrow.

What a great little rekliable fun car
Bought this used about 8 years ago and apart from minor faults seem to improve with age.I also have a V8 Jaguar but drive the Mercedes most of the time just for the fun. I live in a sunny climate and hardly ever have to close the roof. hard to believe this car is now 17 years old.

Greated by nice salesman that took me on tour of vehicles, then a quick test drive.
The most underrated high performance car
A pure joy driving experience, with beautiful lines. Hand built motor. Great handling. 0-60 in under 5 seconds. Fit and finish is very good. Older body style remains a classic.

European Engineering treats you like family !!
I was looking for a quality car for my wife & daughter to drive. I was a "newbie" at car-buying & financing. Luca went way over required to make sure that the car that I selected was safe, legal, insured & registered correctly according to Mass State regulations. I DO recommend Luca & European Engineering for your next car!
Love.
After driving some serious junk, I finally had it and bought my 2003 SLK230 Kompressor with 75,000 miles. Solid German engineering. Performance and handling are perfect. Understated in all the right ways: purrs quietly but packs the power of a supercharger. Even the sound the doors make when they close screams attention to detail. Pretty sure if someone totaled it I would buy another one just like it. Cons: seats should never have left the factory without adjustable lumbar support (very disappointing). Leaking self-dimming mirrors should have been recalled. Few spots of rust on the roof that I didn't notice until after I bought the car, so make sure you look carefully.

I recently purchased a Tesla Model S and couldn’t be happier with the overall experience. Owen was very knowledgeable and helped ensure that the whole process went smoothly. He answered all my questions and took care of my trade in. I highly recommend both Carmel Motors and Owen.
