The OEM production paint at that time was acrylic enamel, now termed "single stage". With the addition of a "hardener" additive, it can look amazing with a "hard shine" better than OEM.
BC/CC takes less color coats, then using the top coats of CC to get the allegedly added UV protection and the slick shine they all seem to have. All with about the same total build thickness. What about matching by your paint supplier?
What paint style do you normally shoot? Cost differences? Whom are you choosing to please?
About that last question . . . at this time, so many people consider BC/CC to be "the standard" as to shine and such. To them, anything less, even if not OEM-production in orientation, is sub-standard. ALL for the same perceived price and efforts. "So why not go with the BC/CC?" to them.
I always appreciated when an owner takes efforts to be true to the model year with the paint they put on the car, as to type. I smile, especially if it is done well. That's just me, but your car is not my car.
Just some thoughts and observations,
