Why buy a rebuilt engine or transmission from us when your mechanic says he can do it cheaper? Because at Automobile Atlanta, we don t compromise your rebuild with substandard parts or machine work. We go overboard in replacing parts your mechanic would never think to or can t readily purchase. Plus, from years of experience, we know what wears out. Our rebuilt engine or transmission will, with care, last as long as the new factory one. Our setup is without compromise. We have invested thousands in Porsche factory tools to insure our engines and transmissions are spot on . Finally, they are extensively checked during each step of the rebuild process so your new engine is ready to bolt-in and drive away. Rebuilt engines and transmissions need a 30 day lead time and we deliver anywhere in the world. All engines are sold on exchange basis of a like core.
