I recently purchased a used CADILLAC STS engine from this vendor and I must say, I'm thoroughly impressed. The engine was in superb condition, much better than I expected for a used part. It was well-packaged and shipped promptly, arriving within the timeframe promised. The customer service was outstanding; they answered all my questions and ensured I was satisfied with my purchase. I installed the engine and it's been running smoothly with no issues. Highly recommend for anyone in need of a reliable used engine!
