It’s kinda hard with cars ending in numbers. We need a crash course on 1337!
1 => L, I
2 => Z
3 => E
4 => A
5 => S
6 => G
7 => L, T
8 => B
9 => … g
0 => O
There was an explanation about numbers, somewhere. It’s assumed that the last letter is the last letter of the number written as a word:
1 - one, E
2 - two, O
10 - ten, N
20 - twenty, Y
100 - hundred, D
…and so on
