Yeah, the new pillars are thicker, but front-to-back, not side-to-side, so from the outside not much difference visually between old and new. My car (Dodge) also has the thickness in the pillar going front-to-back (actually sort of at a 45 degree angle) instead of side-to-side, so there's no bad obstruction.
Hey, they have to hide all of that mandated safety structure somewhere!
But you're right about the new cars being so much tighter. My '67 Impala feels like it has a chassis made of spaghetti. (It's a convertible, so it's even worse!) And brakes on the old cars are so much worse than new car brakes. In fact, if you're not used to them, brakes on an old car can be downright scary!
