A good point, so I just looked it up. This April 1991 ad [0] shows 386 desktops with a hard drive at around $2000 in 1991 prices, and the comparable 486 models with a hard drive start at $7300.
To put that in perspective, $2000 in 1991 is $3700 in today’s dollars, and the 486 would be a staggering $13,500 today.
