Alvins is great! Honest, open and skilled, they diagnosed my 09 Audi A4 quickly and accurately. Unfortunately after diagnosis, I am going to scrap the car, but they were quick to reach a conclusion I was almost already assured was inevitable. They didn't try to get me to unnecessarily spend money or lead my down the wrong path, which Ive heard is common with the type of failure my engine sustained. Will be taking my cars to Alvin's whenever the work or diagnosis is beyond my personal skill level. Thanks guys!
