Did I mess up buying a $2,500 C55 AMG?

I picked up a C55 AMG for $2,500, and it came with a problem. In this video I go over the purchase, what I knew going in, and then run a leakdown test to figure out what's going on inside the engine. The results show low compression in cylinders 3 and 7. I walk through how the leakdown test works, what the numbers mean, and where the air is escaping, so you can see how I narrowed it down. Was it still a good buy? Let me know what you think in the comments. Subscribe to follow along with the rest of this C55 build. #C55AMG #Mercedes #AMG #LeakdownTest #ProjectCar
