I am not disputing the fact that the conversion is good or that there are excellent performance improvements.
On any aircraft costing $100s of thousands or $ millions! residual values have a major impact on the purchase decision as you stand to loose far more than any perceived saving by improved performance or mission capability.
That is the stumbling block as you are taking an aircraft worth maybe $2-300,000 spending a $million plus and you still have an old Citation which is no longer a Citation 1 but What?
If you want to buy such an aircraft let someone else spend the $ s and when they cannot sell for the reasons I have given offer them a third of their outlay only then will it work.
