Any DuPont jobber should be able to pretty much give you a formula match in
acrylic lacquer or acrylic enamel for a stock TR-6 color.  However, since
you're considering a base coat/clear coat, I assume you're considering a wide
range of colors.  In any event, if you pick something on a car within the
past 35 years or so (some much older) they should be able to mix without a
computer match.  Beware a computer match, if you're really critical of an
exact match to some color.  Colorimeters are still not that good, and you may
be disappointed.  Get a quart first, and spray some out on a large panel
(scrap, etc.) before having a whole gallon mixed.

Imron, or other polyurethane is great for good looks (if there are no
imperfections as sprayed) and durability.  However, you'll not be able to
spot repair it very well, and will likely have to do whole panel repaints if
you ever need to touch something up.

Acrylic lacquer is good for a DIY'er, and can be rubbed out and repaired ad
infinitum. However, it chips awfully easily, and after 10 years or less,
you'll probably be thinking about repainting again.

Acrylic enamel, with a "gloss hardener" (polyisocyanate) additive approaches
the gloss and durability of polyurethane with good repairability.  It's much
easier to spot in and rub out later than Imron, etc., and yet holds up well
and shines well "as sprayed".  It was developed to combine the best qualities
of acrylic lacquer and enamel, and with the gloss hardener additive adds some
of polyurethane's good characteristics too.

Base coat/clear coat is pretty.  It isn't terribly easy to touch up -- you'll
likely have to do whole panel repairs or get really good at sanding and
feathering back to expose the layers and be able to repair it well if you
ever need to.  Probably not the best for a daily driver or one you want to
paint and maintain yourself, but if that's your choice, it can be put on and
repaired by a good shop.

Good luck!!
