“Shopping around paid off — John's Mobile Auto Glass came in under everyone else in Diamond Bar. They handled the insurance claim so my out-of-pocket was basically nothing. Worth every minute of comparison shopping.”

“Priced my windshield at Tran Auto Glass and two other shops — no contest. The mobile crew came to my job site so I didn't lose a day of work. My wallet and my windshield are both happy.”

“The free estimate from Cars Windshield was hundreds less than the dealership wanted. The tech arrived on time and had the new windshield in within the hour. That's how quoting a job should work everywhere.”
