Why buy your Buick engine from us
Used Buick engines are among the most-requested units we stock, and we keep a deep, VIN-cataloged inventory across the model years — so whatever Buick you drive, we can match the right engine to your exact vehicle.
Each engine comes from a low-mileage donor we source through suppliers we've vetted ourselves. It stays in that vehicle, protected, until you confirm your order — only then do we remove it, test it, photograph it, and send you those photos to approve before anything ships. Because similar-looking units can differ by generation, drivetrain or options, we always match yours to your VIN so the right one reaches you the first time.
The result: the same engineering you'd pay dealer prices for, at a fraction of the cost, shipped free on a heavy-duty pallet to anywhere in the lower 48, and backed by our written warranty of up to six months.

Before you buy: 5 things to check
How it works
Frequently asked questions
What if the engine doesn't fit my vehicle?
We match every engine to your VIN before it ships. In the rare case a verified unit doesn't fit, we'll find you a replacement or make it right.
Do I see photos of the actual engine before it ships?
Yes. Once your order is confirmed we remove and photograph your actual engine and send the photos for your approval before it leaves us.
What does the warranty cover?
Up to six months from delivery, depending on the unit. The exact term is on each product page — ask us about extending it.
How long does delivery take?
Most orders are prepped and shipped within a few business days of your approval, then a few more days in transit — fully tracked.
Is shipping really free?
Yes — free freight to all 50 states, included in your quote, with no surprises at checkout.
Do I need my VIN?
It's the surest way to guarantee fitment. You'll find your VIN on the dashboard, the driver's door jamb, or your insurance card.
