Chiming in a few years late, because I just saw this thread:

For several years after I got into C&V bikes (fifteenish years ago), I picked up bikes off CL, fixed them up, and resold them. It all started with my daughter’s Miyata, a 1986 110 mixte, which cb400bill helped me acquire from its original owner. That was such a nice bike, and the whole serendipity of it (original owner’s dad had bought it for her) that it may have colored my perception. But the bike really was a jewel, in perfect original condition, the original BB grease still good! Our daughter took it to college in 2009 and still has it!

Over the next several years ten or a dozen Miyatas passed through my hands, and it really struck me that Miyatas seemed to turn up in better condition than other vintage bikes. The quality of the paint and construction was probably part of it, the bikes stood up to wear really well. But also it seems like original owners tended to keep them longer, and owners in general took better care of them. Of course even when Japanese bikes were marketed on price, Miyata was a ‘bike shop’ brand.

RN I’m on the lookout for a pair of Triple Crosses, the subject of the OP’s, um, OP, to fix up for trail/gravel riding for myself and my wife. And I am also very tempted to buy a minty Miyata Carbon in my size that someone down in N Carolina is selling. (Thanks, ‘are you looking…?’ thread.) I don’t even know if I would like a cf frame bike, never really thought of buying one, but it’s a Miyata, and when am I ever going to see another?
