San Antonio's used car market is large and active — USAA employees rotating out, military families PCS-ing from Randolph and Fort Sam Houston, and a steady supply of private sellers across Craigslist and Facebook Marketplace. It also means a steady supply of vehicles that have been driven hard on IH-35 and 281, deferred maintenance because of the cost of living squeeze, or flood-damaged vehicles from the 2024 and 2025 flooding events that come back to market with cleaned titles. A $125 inspection fee is cheap insurance against a $3,000 surprise.
Danny meets you at the seller's location — private driveway, dealer lot, or parking lot — and spends 60–90 minutes on the vehicle. He scans all computer modules (engine, transmission, ABS, SRS airbag, TPMS) for stored and pending fault codes. A seller who recently cleared codes to pass a parts-store scan will show pending codes within one drive cycle — we catch those. He inspects the underbody for rust, frame damage, and signs of prior accident repair. Paint overspray on door jambs, mismatched panel gaps, and undercoating over welds are all accident indicators that CarFax won't catch.
Fluid condition tells a story: dark brown, gritty transmission fluid in a "well-maintained" vehicle means the transmission has been neglected for 60,000+ miles. Milky coolant means a head gasket leak. Sludged oil means infrequent changes. These are negotiating points — or walk-away signals.
Most buyers never scan the airbag module. A deployed airbag that was "repaired" cheaply often leaves the SRS light disabled — the sensor is present but the airbag canister behind the steering wheel is empty or stuffed with foam. We scan the SRS module and pull live data to confirm the airbag system is functional. We've found this condition on San Antonio Craigslist vehicles more than once.
Every inspection ends with a written digital report with photos. If we find a leaking CV boot ($200 repair), worn front brakes ($199 per axle), and a P0128 thermostat code ($150 repair), that's $550 in documented deferred maintenance. You show the seller the report and negotiate $500–$700 off the asking price — or you walk away knowing why. The $125 inspection fee becomes leverage worth multiples of its cost.
Flat rate: $125 — covers the full inspection and a written digital report with photos. No add-on charges. A compression test (for high-mileage engines over 150K miles) is available for an additional $50 and is worth it on any vehicle you're seriously considering. We travel to any location in the greater San Antonio area with no travel fee within 35 miles of central San Antonio.
Castle Hills (78213) is inside Loop 410 on San Antonio's northwest side — a high-density area with active private car sales on Facebook Marketplace and Craigslist. When you find a vehicle worth buying, Danny meets you at the seller's address anywhere in Castle Hills, Vance Jackson, or the surrounding area. He spends 60–90 minutes on the vehicle and hands you a written digital report with photos before you make any decision. A $125 inspection has saved our clients from $3,000–$8,000 mistakes more times than we can count.
All OBD2 computer modules scanned (engine, transmission, ABS, SRS airbag, TPMS), underbody inspection for frame damage and rust, brake pad and rotor condition, fluid color and condition, tire wear patterns, CV boot integrity, belt and hose condition, and paint overspray on door jambs and wheel wells (accident indicator). We check what CarFax can't — the current mechanical condition of the vehicle in front of you today.
