About On Site Mechanic
Mobile auto repair built around honesty, bilingual service and showing up where the vehicle already is.

Mobile Auto Repair
On Site Mechanic was built on a simple idea: a broken-down car should not cost you a tow, a rental and three days of your life. Ivan Chavez brings the shop to you — driveways, parking lots, apartment complexes and freeway shoulders across Greater Houston.
Every job starts with a straight diagnosis and a clear explanation — in English or Spanish — so you know exactly what you are paying for before a single bolt is turned.
