Not sure what's not exotic about it. If you own one you'll notice you get just as much attention as any V8 Ferrari or V10 Lamborghini. Is it the most exotic looking? No, but lots of super expensive "exotics" are pretty tame. It also sounds about 100x better than the 488.

If you don't like the looks at all, then I guess nothing will change your mind, but 9 out of 10 times someone offered the keys to an R8 or a high-end 911 will always go for the R8. The R8 has been proven to be a very successful car.

Value is of course dependent on where you live. It's better than the Huracan and in the US it's probably anywhere from $60-100K cheaper than a Huracan/488, and you don't have to jump through any hoops whatsoever. Can walk into a dealer order any car with any options at MSRP all day, every day, and the options are waaaay cheaper. Compare PTS on an R8 with a 488/Huracan. Is a 488's special-ness worth $100K more than an R8? Maybe, but you can just make the same argument that an Aventador's special-ness is worth $100K more than a 488.

There's little point in saying a car that's vastly more expensive is more "worth it."
