1-2yrs later, what would you have installed/added

[patrickt]

Those would be items that make routine, or less than seldom, maintenance tasks easier. For example, with a Jag rear changing out the rear pads can be difficult if your particular car does not have an access door. Changing out the rotors even more so. Likewise, if you have a Turkey Pan and it is not a two-piece removable TP, tuning your carburetor can be a real nuisance depending on what particular carburetor you have. And these cars live and die on their carburetor's performance. With my ERA, and having studied it for twenty years before having it built to my specifications, the only customization that I would have added "from the factory" is a trap door on the tunnel, just like some Jags have, that allow for easy servicing of the front driveshaft u-joint. That's a peculiarity of the ERA cars with the custom outboard braked rears with the integral emergency brake. That would not apply to most other cars. So, to answer your question, most of the answers to your question will not apply unless you choose exactly the same car as the writer, with pretty much the same options, and pretty much the same vintage. The only exception to that is the big block versus small block. I have never heard anyone say "dang, I really wish I'd gone with a small block." Of course this is only true for 427 style cars, not FIAs. A small block in a 427 car is a catastrophic mistake.
