FAQs

Do you coordinate with the seller?
We’ll help coordinate the inspection by reaching out to align a time and place and confirming what we need on arrival. Final access and approval remain between buyer and seller—we don’t manage every part of the seller’s schedule.

What happens if it rains?
We inspect in normal rain and note any limits. In extreme rain or unsafe conditions, a full inspection can’t be completed unless there’s a covered area for our technician to work. Without cover, we’ll complete what’s safe and reschedule remaining road-test or electrical portions as needed, with clear notes.

How long is the drive?
Level 1: 0–3 miles. Level 2: ~10 miles. Level 3: ~25 miles to force a true warm-through and repeated cycles.

What do the codes in the scan mean?
You’ll get a full DTC list by module with each code labeled current or history, explained in plain English with context from the road test.

What do you not do?
We don’t provide bodywork estimates, emissions guarantees, or promises about seller behavior. A PPI is an expert snapshot of condition on the day we inspect—not a warranty.

What Makes Us Different

Why a Mobile PPI (Pre-Purchase Vehicle Inspections) Matters in San Antonio

A loop around the block doesn’t show heat-soak issues, stop-and-go shudders, or warning signs that lead to big bills once the car’s yours. We inspect in the real world—Texas heat, highway speeds, city traffic—so you know how the car behaves where you’ll actually drive it. No showroom tricks, just how it runs, shifts, stops, cools, and ages under real conditions.
