I have a preference for guns as old as me
but maybe I'm just plain wrong about these new "classics." How do they rate - shooting, fit, and finish wise?

I like this analogy, because in spirit, I can respect it. But in fact, the '01 emissions restrictions would INHIBIT the natural performance of the '63 engine. There is no such performance loss in the new vs. old 'classic' revolver. You might not WANT the IL or the MIM etc, but the fact is, the package PERFORMS as good or better and I would argue with tighter tolerances in machining.They're pretty, but to my mind it's like buying a '63 Vette with '01 smog equipment.

I had a chance to shoot two .45 Colt M-25's side by side, my old one and a new classic model with all of the stuff purists hate. The new M-25 was better fitted, tighter, had a better trigger (amazing!), and generally shot better. All good. But the new M-25 had those Godawful laminated stocks, IL, and MIM parts. The performance of the new gun was surprising and pleasing, but I still prefer my old one.
I have bought model 22-4s and 21-4s and would rate them as excellent in finish and shooting. I wish I still had them but that old buy,sell, trade routine I used to have got the best of me.
A point to consider, I had a "bare bones" 1964 GTO, bought new, and driven, over 250,000 miles, that would out do the 2013 Chyrsler 300, that I currently drive, in every respect, other than pure unadulterated aggravation, and has nothing at all to do with classic revolvers.

I consistently find the older Smiths for less than half the price of a Classics. . .all the J and K frames pre and post war. I can't figure out where the market is for the Classics line. Maybe the N frames, but I find older ones cheap too. Paying $250-$300 for really nice older Smiths. Why would I pay $700-$800 for a Classics? My Son says a newer gun is more dependable and less likely to break. If that is the case and a person is worried about dependability, just buy one of the newer Smith J frames for under $400. I bought my wife one. It's light and seems to be dependable. I have never seen the niche that the Classics fit into.
Run both of those vehicles head on into a tree at 35 mph and tell us which one is better. Just make sure to do the 300 first so you'll still be alive to do the Goat. And before you try either one, tell us how they compare on: fuel mileage, tire wear, braking and steering, and tune up intervals, (bet you didn't drive 100,000 miles on a set of spark plugs). For the record, I had a 1966 GTO, also new from the factory, so I already know the answers to these comparisons.
I do agree that it has nothing to do with revolvers with one minor point: both the auto industry and the firearm industry had greatly benefited from modern machining processes.
