From the alternator that quit on Highway 1 to the brake pads you need this weekend — we've got the parts, the tools, and the know-how to get you back on the road. No guesswork. No hassle.
Whether you're a DIY mechanic or a professional shop, we stock the components you actually need — from routine maintenance to the hard-to-find replacements.
Belts, hoses, filters, spark plugs, sensors, and everything between the engine bay and the oil pan.
Pads, rotors, calipers, struts, shocks — parts that keep your vehicle stopping safely and handling smoothly.
Alternators, starters, batteries, wiring harnesses, and lighting — the systems that bring your car to life.
Fluids, filters, clutch components, axles, and the parts that transfer power to your wheels.
Hand tools, diagnostic equipment, shop supplies, and the gear that makes the job go faster and cleaner.
Factory-spec parts for the purists, and quality aftermarket alternatives that deliver value without compromise.
We know the difference between needing a part and needing the right part — and we'll help you figure out which one that is.
Bring us your old part, a photo, or just describe the problem. We'll track down exactly what you need — and tell you if you actually need it.
Can't find it on the shelf? We order from national and regional suppliers. Most parts arrive within a few business days, often sooner.
Our team has real hands-on experience. We'll walk you through the repair, point out the common pitfalls, and save you a trip back to the store.
Heavy or bulky items? We offer local delivery within the St. Augustine area so you don't have to load it into your truck yourself.
Motor This Motor That started with a simple idea: St. Augustine deserved a parts store that treated every customer like a neighbor — not a transaction. Whether you're changing your own oil or rebuilding an engine, we want you to walk out with exactly what you need and the confidence to install it right.
We carry parts for domestic and import vehicles alike. We check our inventory so you don't have to make three stops. And when we say we'll have it ready, we mean it.
"I pulled into the parking lot with a check engine light and no idea what was wrong. They looked it up, told me exactly what to expect, and had the part ready before I finished coffee. That's the kind of place this is."
"As a weekend mechanic, I appreciate when a shop doesn't treat me like I don't know what I'm doing. These guys give honest recommendations and fair prices. I keep coming back."
"Needed a part for an older model truck that everyone said was discontinued. Motor This Motor That tracked it down in two days. Saved me from buying a new vehicle over something that simple."
