How to build a retaining wall flush against a sloping driveway?

I'll try to explain this as best I can. I have a garden that extends off of a turnaround area of my driveway, level with the driveway. The lawn around the garden slopes down away from the driveway. The garden itself spans along about 35 ft against the driveway. The current garden is dilapidated and outdated but I like having a garden there. So, I'm keeping the general footprint of the garden but updating it, beginning with a new retaining wall. I'm using the dry-stack, prefab 4x12" blocks and 2x12" caps that you can buy at Home Depot. My problem is that along the 35 ft that the garden and driveway intersect, the driveway slopes down about 4-5". Given a level wall and no step-ups/downs, I cannot get the ends of the wall to be flush against the driveway surface at both intersections. Do I purposely make the wall not level and attempt to pitch it the same as the driveway? That seems very difficult and building a non-level wall seems like a terrible idea. However, both ends will be flush against the driveway surface and at 4" across 35ft, I don't think it will be noticeable to the eye. Another option I'd considered is bookending the wall with something decorative to disguise the wall and driveway not lining up? Any other ideas, options, suggestions? Thanks.
