Brought my 300zx here in January for a stereo install, and to have my seats and exhaust bolted up. The stereo stopped working after about 30 minutes and when I took it apart, the wiring looked like it had been a project in a high school wiring class. The driver seat bolt was cross threaded, and the passenger seat no longer adjusts forward or back. He charged me $280 for all that. If you value your car and the work done to it, do not bring it to Mario.
I drive down from San Francisco to 38carmodz to get service done right
