These two projectors are not comparable... car analogies or otherwise.
$699 for a 720P PJ... 3D or 2D... is a pretty low-bar projector.
Most "entry level" Home-Theater worthy 1080p 2D projectors start in the $2000 range. A decent LCOS or SXRD or DLP solution will run you between $3000 and $10,000 right now... and that's just for 2D. In fact, the 2D LG projector that this new 3D model is based off of is $5K, and since the 3D projector is basically 2-machines-in-one, the $10K price is actually pretty reasonable.
Also, besides the vastly different image quality between a 699 and 10K machine, the method of producing 3D is very different: the LG is using polarized light with no flicker, which would make it easy for a large crowd of viewers since inexpensive glasses will work without the need for active LCD eyewear.
Polarized solutions will be expensive with dual-engine light paths, but will provide optimal image quality. There will also be lesser cost single-engine polarized that alternate left/right even though they use polarized light) as well as active shutter wear front projection systems... these latter two should cost less but there will naturally be trade offs given the different designs.
I doubt that any videophile serious about home-theater and good image quality would be satisifed with a $699 projector with today's technology, given that even 2D projectors at that price point have very compromised image quality.
