What's a good way to say "the front right 'side' of a car"?

For context:

There was a collision and the front left side of A's car hit the back right side of B's car.

The "front right" of a car isn't really a side so much as it is a corner, yet corner doesn't really sound good in the above context.

Solution 1:

In the motor industry, your problem is solved by creating the adjectival noun phrases:

Offside front, nearside front, offside rear, and nearside rear.

See, for example,

In this commonly used nomenclature, your particular front right side (or corner) is the “offside front”.

For those who dislike offside and nearside, I suggest they be trivially replaced by passenger side and driver side.
