Why is anybody getting worked up about this? He's 21 and in college, has no Kirkham, no SOHC, no money and no plans of buying or building anything for years and years. It's interesting yes but ultimately meaningless as all these prices will be different 5 or 10 years from now. It should have been presented as nothing more than hypothetical to begin with as any info given will be out of date and this thread archived and forgotten long before any of it gets used as anything more than a spreadsheet.
And before I get flamed for beating down a dream I've wanted a Cobra since I was 14 (1980) and by golly I finally got one. After I got married, bought a house, started a business, had kids etc, etc. Only took 24 years!
