“George just completed replacing a master cylinder and brake booster on my son-in-law 01 Isuzu Rodeo with an unexpected quick turnaround during a winter freez week. This same vehicle, i purchased about 5 years ago. I took it to Cossios to get it diagnosed by George. He verified that the trans was bad. I asked him at that time was it worth putting in $1500 into the vehicle? George stated if we were planning to keep it. Yes was it was worth it due to the vehicles low milage. We went ahead with the replacement of trans and have had no major issues since.I have done business with Mr George and his father over several years. Atleast 3 trans replaced in different vehicles,general mechanical work on our daughters vehicles. Fortunately we have yet to have one slight of any bad experience. His prices for all his work to be done has been favorable but i appreciate the most. Is the handshake of an honesty mechanic who is knowledgeable and will give you great service with warranty. I highly recommend Cossio's.”
