Are they? I'll agree if you are saying it if there's a "Market Adjustment" or "Additional Dealer Markup) but not so much when you look at what you now get as standard on a vehicle that used to be only the top trim or even luxury models or, in some cases didn't exist until recently.
I just bought what is likely my last vehicle and just for giggles and grins I compared the price with my first new car, a 1976 Grand Prix. That car was pretty much bare bones, crank windows, AM radio, an interesting engine the State Police didn't like and a couple other things. Adjusted for inflation it was more expensive than the new one I just got that has most of the current bells and whistles, some of which are mandated (ABS, Stability Control, back up camera, etc.) and some that aren't (cruise control, Blue Tooth, AM/FM/SAT radio), power windows, locks and seat, etc. The only added options were the self-dimming mirror and floor mats.
People say the same for trucks but again look at what you get on a new truck, and what it can do, compared to the ones even twenty five years ago.
I drove some of those bricks with wheels, albeit 1960s/70s vintage, and I'll take my 2014 F150 over any of them, especially the International.
