You hit the nail on the head EVERY INCH OF THE WAY, Sir. ( My Dad was as a "Caddy" man, though. But he DID buy his. 'Had his last one almost 20 years. He wouldn't part with it. It's still out at the folk's place. )
AND MY DAD WOULD HAVE SAID THE EXACT DADGUM THING ABOUT ME BUYIN' MY GT AS YOUR'S WOULD HAVE!!!!!!!!!
In fact, when I bought my 'Vette ( 435/427, 4-spd, "T- top") back in 1968 he said almost exactly that! He was actually leaning against the car kinda looking all bored 'n' stuff as the salesman & I came out (to put a "sold" sign on it) and Dad said, "So...where IS this $6,300 wonder car you're buyin'?" And I said, "Uh, Dad? You're leaning on it." With that he JUMPED away from it, looked at it in astonishment & said (you guessed it!), "YOU'RE PAYING $6,300 FOR THAT???????!!!!! Aaaaaah! You're NUTS!" ...But HE smiled from ear to ear whenever HE rode in it! And he always had that little devilish twinkle in his eye & that "cat that ate the canary" smirk on his face whenever he saw the car - or whenever it was even mentioned.
I could just see him and Mom in my mind's eye again last July kinda quietly witnessing me buy the GT ... 'sorta smiling (smirking?) a bit & kinda shaking their heads a little over THAT outlay for a car not much bigger than that old 'Vette way back when. Dad probably said (No! I KNOW he did!), "Mildred, just look at this. After all these years that darn kid hasn't learned a thing."
I think it's a "parent thing", don't you?
God rest them both.
Sorry for all the blather. I'll shut up now.
