OP, what you should understand that from birth we are programmed in very subtle ways to be continuous Shoppers/Buyers. As a result we are never truely satisfied with the goods we buy as there may be a point where something "better" is available or introduced. Never mind in our case if what we already have could/should completely satisfy our needs for a fun interesting car.

So do not let yourself have "Buyers Remorse" over a purchase you fully decided to make. It's not easy to fight that, but can you see it never ends?

Some T4 buyers will want the V6 or V8
Some V6 buyers will want the V8.
Some V8 buyers will want the ZL1.
Some ZL1 buyers will want the ZL1/1LE or the new GT500 or the Demon, etc

With regards to current Camaro owners:
Many of those buyers will want the upgraded SS with the 10 speed and a facelift and new toys.
All may want the 7th gen Camaro eventually.

But consider this, you already own a Cadillac based car with a great engine making over 300 HP, that handles great stock, and gets great gas milage and is reasonable to insure. In fact Camaros are now considered real "Sports cars" by many journalist. These cars are so good at everything, where we go from here is only small increments of goodness. To me the only thing missing is a car we can see out of, and a usable back seat.

So OP reflect on your desires, enjoy the very fun car you already own, and save all that money you would spend on an upgrade and invest it. Then one day you might not have to worry about buying any version of a Camaro. Otherwise we are treading water and in the end left with very little.
