Steer clear of MM. (engine master in German...)
Do not walk away, but run.
You are right to be sceptical. There is a good reason that the new owner is selling his newly rebuilt ride... He probably discovered a major problem with the engine, then tried to come to a solution with MM during the next eleven months...
After being left in the cold he decided to sell his misery...
Or something like that...
Don't buy it, google MM (use the full name), lots of bad reviews, lots and lots.

Like Grady said, educate yourself, and buy confidently. Then and only then you will enjoy Porsche ownership.
This place is the holy grail of Porsche info, read, ask, learn!!
Good luck in finding the Porsche of your dreams
