In my experience...
The touch points in the car (that would have had victim blood on them were it not for the fact that the killer was likely wearing gloves during the crime) would be easily cleaned. Those would be door handles, steering wheel, ignition area, seat belt clips, gear shift, etc. There are other things that could be done to decrease DNA retrieval from those use points, prior to the crime, but I'm not here to give lessons on how to get away with crimes.
It's still a risky business (cleaning up) but not an impossible one. If one of the victims had actually been transported alive in the car, it would be harder to clean up.
It's the preplanning in this case that really helped stymie efforts to get DNA from a vehicle that was likely cleaned many times between Nov 14 and the final week of December.
Some day, we'll have more data on how much DNA is average or typical for a steering wheel, given the mileage on the car and the length of time of ownership. But given that some people really do clean their entire car (or have it professionally detailed - sometimes once a week), it is of little evidentiary consequence and merely suggestive.
