I would disagree with this.
We've done "drive in movie nights" with friends and neighbors, and I use my old Infocus SP-4805 (480p, 700 Lumens or so). I set it up to project onto the side of my neighbor's gray house about 12ft wide. We have to wait until it is dark (not just sunset), but who went to the drive in before dark anyway? Once it is dark (a few weeks ago, we started at 9:20 or thereabouts), it was plenty bright.
For audio, we have everyone bring their boom boxes, and I use an FM modulator out of the portable DVD player (old Toshiba SDP-2000 with component progressive out), and away we go. Low budget, but everyone seems to love it!
Personally, I don't think I'd buy a new projector for this purpose. There are a ton of low-hour 480p and 720p projectors out there in the $500 or less range, and if the outdoor use kills it (I worry about the dew, which is a problem some nights), he won't be so upset.
