For the two front digits, there are 8 possibilities under the conditions of the problem (all except 6 and 9). Each of these 8 digit pairs can be coupled with one of the 4 combinations AB 69, AB 96, AD 69, AD 96. Therefore, the maximum number of vehicles that meet the conditions of the problem is $4 \cdot 8=32$.
