Comparing a mid 80's 911 to a 993 is kind of like comparing a 356 to the mid 80's 911. 356 Porsches are bring big money compared to mid 80's 911 and there is not near the technology in a 356, but it goes back to supply and demand. It is increasingly difficult to find a good, solid 356 and they are an icon (IMO) in the sports car world, therefore, prices are high. It is also, slowly but surely, becoming increasingly difficult to find a good mid 80's 911, not to mention a longhood and their prices. I guess the point I am trying to make is just because a car is newer with more technological advancements does not dictate the price consumers are willing to pay. Well for me, I love them all....
All the best,
