Both x and y boxplots are correct
and in particular the median of the x box is at 6 which is confirmed
median(aa$x)
[1] 6
Now I do only one addition to the scatterplot: I add xlim
scatterplot(aa$x,aa$y,smooth = FALSE, grid = FALSE, frame =
FALSE,regLine=F,xlim=c(0,8))
This causes the boxplot on x-axis to be in error:
1) the lower whisker starts now from zero
2) the median is between 4 and 6 and no longer at 6 as before

(1) Please present data using dput(); this makes life a lot easier for
your respondents. (See posting guide.)
(2) Please do not post in html. (See posting guide.)
(3) I agree that this looks like a bug.
(4) Email about issues like this should be sent to the maintainer of the
package in question (see maintainer("car")) and not to r-help.
cheers,
