Hi guys, currently working on this trophy list myself, and the geared up trophy is nothing short of a pain in the arse. I hit level 50 today, and I am still 50,000 coins off being able to buy all the items. I'm going to write a guide with some advice for the fastest and easiest ways to achieve this platinum, as I have spent an extensive amount of time this month going for it, and there have been very few videos/ written guides with methods for achieving some of the more tedious trophies.
Can confirm that Geared Up requires all levelling unlocks. So be ready for a grind!
