Modern cars are all great for safety, reliability and performance (horsepower, handling, MPG).
You also get add ons you don't need. You get a radio for $1000 that an aftermarket radio could outperform for 1/2 (1/3?) the cost. My 1st 3 (used) cars ('74, '76 and '85) came from the dealer w/o a radio. I borrowed a '73 Corvette once and it had an AM radio w/ 1 speaker above it in the dash.
Power windows (& locks) instead of manual ones. A sunroof w/ motors to retract instead of a simple pop up installed later (which might have less safety than the builtin). Air conditioning, heated seats, powered seats, powered and heated side mirrors that cost 10x the old manual ones.
Those addons are why the $23k car is a $30k car. I definitely enjoy them, but if I was just out of college, saving 1/5 on a car is 2-3 months rent!
