Resale value is a huge factor in my purchasing/altering decisions. Has nothing to do with gear snobbery. I'll always buy used when I can to take advantage of any depreciation. I then maintain what I bought because, A. I like my stuff to be nice. B. I've learned no matter how much you plan on dying with something, you just may have to turn it for some cash at some point. I've never had a massive or endless budget to buy things, so every penny has counted. For a drum example, when I bought my PDPs, They were in great shape and I kept them that way. They were no heirlooms and never will be, but recouping what I spent on them helped me get into the next set.
Depreciation on cars is the same. Never sold one and broke even, but I've far from lost my shorts on any transaction. Sadly, most fun cars end up being worth close to zero in a few years, so I've had to opt for vanilla I've always been meticulous about my stuff, but when I was out of employment with prospects becoming more hopeless by the day all those things I bought right and cared for meticulously kept me and the wife afloat for months. Onkyo Integra stereo system => bought used, recouped every penny a decade later. Premier drums and Zildjian cymbals and all DW hardware => recouped every penny. I could go on but you get the idea. Resale value is what kept us afloat for months.
I've always limited my "wanter" and don't buy with the intent to sell. However, life throws curveballs and you can't get too attached to things. If you find yourself out of options, being able to recoupe close to your original expenditure can be the difference between surviving and dying on the vine. In today's economy where things can go bad at any time (insert 2020 here) and you may find yourself in need, resale should always be a consideration. If on the other hand gear or equipment is used for ones livelihood then that takes precedence. If a tom tree makes you more efficient, then drill baby drill. Heck drill three tom trees, who cares and why in the world would you opt for the back breaking 10x the weight, restricted movement option when you have a versatile light weight option. The DW sliding tom mount was as obnoxious as ever produced weight wise. I'm glad they aren't shipping those like they used to.
