I paid about $25k for a tractor that I could've bought an equivalent orange tractor for that cost $35k (real numbers).
Let's say (numbers pulled out of a hat for illustration) mine is worth 50% that in 10 years, and the orange one is worth 65% of its value in the same 10 years.
So, I'd get $12.5k for the red one, vs $22.75k for the orange one. Wow, the red one's value sucks, right?
The red one cost $1,250/year, the orange one $1,225/year; meanwhile I had $10k more to get implements with one than the other (or "invest" it do w/e you want, even at a lousy 2% that 10k is worth more than 12k after 10 years, so if you use that gain then the red tractor only cost a bit over $1k/year, but I'm buying implements, screw investing I have dirt to play with).
I'm just illustrating that "retaining more of its original value" doesn't necessarily mean much - YMMV, the numbers may be different, and you may be one of those lucky guys who "sold mah kobota fer more than I bought it!!1!One!!"
