You're getting old and bitter. Honestly, you sound like an old man who needs to take a nap.
Do we even know how old the owner is? What if he's from your generation, or even older than you?
I'm from your generation (I'm 34) and I don't understand all the immature criticisms of this car and why it upsets people so much. I used to be on the Miata forums and it was the same thing when someone rat rodded their Miata, lots of people got really worked up. It wasn't my thing but whatever.
There are lots of cars out there modified by people of all generations that look terrible to me, but I don't think it really has much to do with how old you are. Look at the "barn find" culture: Older enthusiasts for sure, refuse to even remove the dirt off of some of the cars they find and tow them into a show, and it baffles me, but I just say "Ok, I don't get it but maybe I will someday" and move on.
I hope you don't really follow cars, otherwise you'll find lots of other things/styles that will raise your blood pressure and make you take your medication: lowriders, rat rods, bosozoku, VIP (bippu), drifting, cafe racer style (yes on cars), desert racer/pre-runner, donks, db drag racing, Lemons/Chump Car, vintage racing, hardcore autocross, etc. It's the variety that makes cars so exciting.
