Four of the five among the following are similar in such a way to form a group, which one of them doesn’t belongs to the group?

Q sits at one of the extreme ends. There is only one person sits between Q and the one who faces the person who like Benz Car. D sits to the immediate right of the person who like Benz Car. There is one person sits between Q and R. R like Benz Car. Number of persons who sits to the right of R is same as that of number of person who sits to the left of C. The person who likes Toyotto Car sits immediate left of R. Case-1 Two people sit between T and P. T sits somewhere to left of P. T faces the one who like Toyotto Car. Case-1 One of the people who like Swift Car is an immediate neighbour of the one who like Audi Car in row 2. E sits left of A. E is an immediate neighbour of B. B faces the person who sits to the immediate right of the person who like Swift Car. S and B doesn’t like Swift Car. There is only one person sits between D and the one who like BMW Car. Case 1 doesn’t satisfy above condition. So this case is eliminated. And Case 2 will be the final arrangement.
