After spending $7500 on a major overhaul of my long term love of my 1996 993, I had an electrical problem that looked to be either in the main computer or the alarm system. You could have easily hit me with a $2k bill to replace either or both of these systems, but in fact diagnosed the problem to a faulty battery ground cable. This is real customer satisfaction and why I recommend Renn Haus to everyone I know for service of their special loves.
