Friend is in the market, and came upon a low-mileage 1974 365 BB (Yellow). Question: Given your choice, would you prefer a 365 or 512 version? Let's make it less complicated by leaving the injected cars out for the moment, unless one feels that the injected variety adds significantly to driveability and, perhaps most important, collectability. Which will go up in value more: 365 or 512? Carb (512) or injected (512)? I do not need input on how nice Boxers are. Just discussion weighing the advantages of 365 versus 512, if any. Thanks for your help. Jim S.
