-
Accessories: Consider whether the engine includes vital components like the intake manifold, carburetor, distributor, and alternator. The price should reflect the completeness of the engine.
-
Price: Research the average price of similar engines to ensure you're getting a fair deal. Be wary of prices that are significantly lower than average, as this could indicate hidden problems.
