Not intuitive at all. If the buggy company makes a million buggies a year, they may enjoy an economy of scale that they can't have by making a thousand buggies a year. Therefore, is cars replace buggies, you can have FEWER people want buggies, and the value of a buggy is GREATER.
Again, if you are unconvinced by my arguments, just be aware of the differences in terminology. In Marxian terminology, your phrase "price (exchange value) and value (use value)" is all messed up.
Exchange value = the word value when there is no adjective in front of it = the central level about which the price fluctuates.
In Marx's model, "value" is more similar to the thing that a modern capitalist who trades commodity futures by using technical analysis (the support and resistance concepts) would call a moving average with a long term. Perhaps the thirty-year moving average. The current price oscillates above and below it.
