Let's put given 9 information in a table. The person in Bold
Font will not get the corresponding car unless the persons
in Normal Font get the corresponding cars. Also, the person
will Italics will get the remaining car.

Merc Honda Ford Zen

1 Barry Alan Denzil Carl

2 Alan Denzil Barry Carl

3 Barry Alan Carl Denzil

4 Alan Barry Denzil Carl

5 Barry Carl Denzil Alan

6 Carl Barry Denzil Alan

7 Denzil Barry Alan Carl

8 Carl Denzil Alan Barry

9 Carl Denzil ? ?

Now, let's assume that Alan gets the Merc. Then from (4),
Barry gets the Honda, Denzil gets the Ford and Carl gets the
Zen. But from (7), Carl will not get the Zen unless Barry
gets the Honda and Alan gets the Ford. Thus, it contradicts
the original assumption. Hence, Alan will not get the Merc.

Let's assume that Alan gets the Honda. Then from (1), Barry
gets the Merc, Denzil gets the Ford and Carl gets the Zen.
But from (5) or from (7), it contradicts the original
assumption. Hence, Alan will not get the Honda.

Let's assume that Alan gets the Ford. Then from (8), Carl
gets the Merc, Denzil gets the Ford and Barry gets the Zen -
which does not contradict any of the statement.

Similaly, you can assume that Alan gets the Zen. (which is
contradictory to (9))

Hence, Alan gets the Ford, Barry gets the Zen, Carl gets the
Merc and Denzil gets the Honda.
