Your cost-benefit analysis seems wise to me. A guy I once worked for told me, "Don't measure something with a micrometer if you're going to cut it with an axe." (figuratively)
Thanks for the work you've done with this and for sharing it. I found it very enlightening and accurate enough for my purposes. I was worried about the "conventional wisdom" that the Mk3 Focus would have a higher cost to own due to higher depreciation, but that appears not to be true for the SE trim level I'm interested in buying. That is, as long as I negotiate a reasonable deal in the first place. You helped me understand where that target is, too.
I'm guessing that a higher cost Titanium loaded with expensive options would experience worse depreciation. It seems that anyone interested in one like that should consider using that to their advantage by buying it used rather than new.
