FI sounds great if you drive your car a lot, or drive it in varied climates or varied conditions. With a carb you essentially have one dumb nozzle for the cold or when hot or when at fuel throttle or when idling with no feedback. Of course I am oversimplifying things, but at the end of the day, I just like to cruise around a little in my Riv during the warmer months and that's about it. I'm not driving it in the winter, or at high altitudes or cross country. Set it for one tune and that's pretty good for all of the conditions that I want the car to operate in. If you asked me before I bought the Riv if FI would have been in the cards, I probably would have said yes. Same with disc brakes. But honestly its perfectly fine without those upgrades. If it was a true muscle car that I was taking to the track or drag racing it, then my answer would be different. But it is a gorgeous cruiser for the summer, and it (usually) handles those duties splendidly.
Now having said all that, I still am interested in hearing more about one's adventures in FI Town and how complicated the process was and roughly how much it all cost. I still enjoy seeing how people modify their cars to suite their tastes - authentic (OEM) doesn't really mean much to me.
