I wanted to ask you about this A8 Audi engine.

Hello and blessings of God and His mercy be upon you Dear good people, would you recommend this motor? Is it reliable enough for someone to purchase? What are the motor's pros and cons? Are there any manufacturing defects? How about spare parts—Are they available and what about their prices? And of course, the fully equipped model How much does the fully equipped model cost? Sorry to the owner of the photo Thank you very much
