I'm at a similar place @ 54. I used to chase the toys pretty hard, joke about having conquered land sea and air since when married we had a nice boat for a while, his and hers Harley's, then sold all that and after getting my PPASEL went and bought a used airplane did that for awhile (more expen$ive hobby than boating ...), then a convertible corvette (bought pre-owned), then time to buy our next house in 2006 bigger and nicer. I think it would have all toned down on it's own after 50 anyhow but it got an express boost to "material stuff doesn't matter that much" when she died unexpectedly in 2012 at age 45, I was 49 and our son 22. Combine the survivorship roller coaster with turning 50 and material possessions suddenly took a back seat. I really care about lately is how our son is doing starting his new life after marrying in 2015, how my nieces and nephews are, and my surviving brother and sister (mom dad another brother and sister all r.i.p.). Have focused on faith and being more charitable, and enjoying what more life has to offer. Physically I'm in great shape, and have had a good and complete recovery from my recent motorcycle wreck.
Proposed to my girlfriend last year, we're engaged, and life is happy. But chasing material goodies, for me, is probably on the back burner for good. As has been mentioned already by others, only interested in that which fills a need adequately and maybe one bell and whistle or two don't need the loaded model, etc.
The only exception to this for me would be motorcycles. They feel too personal to me to buy used, so I buy brand new. That's my one vice.
