Flatline is one of the most unprofessional and fraudulent shops I have ever had the displeasure of dealing with in this city. He took my engine in for a rebuild, promising that it would be done in 3 weeks. Not only did he not complete it on time, but he hadn't even STARTED. He also left my engine on the floor, causing it to break parts of the engine. After the fourth week, he (without asking) offloaded my build to a different engine builder. This builder was fortunately wonderful. After I got the engine back from the builder, he then decided to hold the rest of my parts (intake and exhaust manifold, other ancillaries, etc) hostage until I agreed to pay him an amount we had never spoken of before (I had paid the rebuild fee he had quoted me at). Luckily I got MOST of my stuff back without paying him, but he stole my turbo (claiming he had "never got it") and a few other small odds and ends. The whole while, he was completely unresponsive, often taking weeks to get back to me.
There are tons of others with stories far worse than mine, of Dom costing them thousands of dollars, of him stealing parts, and of him lying about what he installed. The man refuses to take responsibility. If I can do one thing on yelp, it would be to urge people to never give him business ever again.
