That's what I noticed as well - we get so many compliments ("what a nice car you have")!, while modern cars that can be twice as expensive to buy and much more expensive to drive (mostly due to the depreciation) never get a second look or compliment.
The other thing people, who are not 'into' classic cars, tend to say, after they hear my car is 37 years old, "but it still looks so good, it's like new!". I then always say: "any car could look like this after 37 years, if only they were maintained properly" which is true of course, however nobody ever replies, they just sort of keep looking amazed.
