Fitment and installation
Fitment first
VIN, engine code, and dress level decide whether a listing is a candidate. Year/make/model is only the first filter. Use the engine locator after you have those details.
Used or remanufactured
Condition class changes price, included parts, and how you read mileage. Compare both against the job, not against a slogan.
Freight is part of the purchase
Engines travel as heavy freight. Read shipping before you choose a residential driveway or a shop dock.
