re: resale value
I don't believe the 8 has a better resale value than the 4. Just because the price is higher doesn?t make it a greater value. One needs to consider the ROI.
The 8 builders nearly always without exception put way more money into their planes so they have to ask for a heck of a lot more. They tend to go with bigger engines, C/S, more instrumentation, and the QB kits are considerably more and many choose that option. 8?s had better ask for more, and they should get more, but only because their investment is greater. That doesn't translate into the 8?s having a better ROI or better resale value than the 4?s.
