Fixed Right.
First Time.
Check engine lights, misfires, oil leaks, and major repairs diagnosed to the root cause and fixed right — the first visit. OEM-level diagnostics, every job documented with photos, written quote before we touch your car.
Diagnosis to Delivery.
Done Right.
Every visit starts with a free 49-point inspection, OEM-level scan, and photo documentation. Root cause found, written quote delivered — no surprises.
OEM-level scans, live data, smoke & pressure tests. We find the real root cause — not just the code. Written report included.
Valve cover, oil pan, coolant hoses, thermostat housing, water pump. Source confirmed before anything is quoted.
Cylinder-level diagnosis — coils, plugs, injectors, VANOS, carbon buildup. Walnut blast when needed.
Engine replacements, timing chain, transmission, transfer case. Major work quoted line-item, done on schedule.
Pads, rotors, calipers, ABS, control arms, bearings, alignment. Torqued to spec, road-tested, documented.
Oil changes, fluids, spark plugs, filters, inspections — OEM or better parts. No dealer markup.

A lifelong car enthusiast with a technician’s mindset, Ryan built his reputation across Florida and Texas before launching PPP in North Dallas.
With 5+ years dedicated to European platforms — especially BMW — Ryan runs factory-level diagnostics, reads the actual service manual, and solves problems other shops have already given up on.
You get straight talk, honest timelines, and work that holds up. Written quote before he starts. Photos while he works. Re-scan before you leave.
Fixed Once.
Fixed Right.
Real clients, real repairs — not marketing copy.
“Ryan found the root cause of my BMW’s misfire in the first visit when two other shops had already failed. Clean documentation, honest pricing, car runs perfect.”
“Quoted up front, finished on time, before/after photos with a full checklist. Nobody communicates or documents like this. My go-to from now on.”
“Two dealerships quoted $2,200 for a coolant leak. Ryan found the actual source — documented everything, done same day. Never going back to a dealer.”
