Hello I need you help¡¡¡ Maserati Superleggera 3700

I live in Mexico City, and a Friend of mine has an uncle that is selling me his Maserati Superleggera Turin 1954, 3700 Coupe, I Know about cars but I am a complete stranger on Maserati and more off course vintage ones, I am posting some pictures of the car, I does needs a lot of restoration, the engine for what they say a piston is broken but the car was running before they toke the engine away, everything is complete, even the interior is original, off course is not in good conditions.

So the questions are many and I will start to ask on how much a restored car like this can be sale??, to restored the car I may find parts like rubbers, electrical parts, wire harness, lights, stop lights, etc. I would like to make a 10 points restoration¡¡¡¡ how much a restoration could cost and who can help me on this journey, stores out there with parts?

The car chassis number and engine is 101142 the owner said that there where just 5 cars like this built?? is that true?

The car can be bought very cheap, He is an old person and he wants to throw away the car, what do you think???

Sincerely

Ricardo
