State Auto Parts kept me updated the whole way and the refurbished engine arrived spotless. Bolted right in and the warranty registration was painless.
The transmission matched my VIN perfectly and shifts cleanly. Took an extra day to get the tracking info, otherwise this would have been a full five stars.
Really impressed with how knowledgeable the support team was about my hybrid setup. They sourced the exact low-mile engine I needed and even included install tips.
