Wife wants to get rid of Yaris! Help!

[CtrlAltDefeat]

Recently we realized that in the near future, we may need to carry 2 adults and 3 children in car seats on a semi-regular basis (like 3-4 times a month if unlucky). As it sits currently, 2 car seats (toddler and baby) fit rather perfectly in the back of our LB, with about a foot between them. A 3rd car seat will not fit, however.

I'm not really sure what to do... I love my Yaris, and have spent quite a bit of time and money on mods for it (quite a bit for me, any ways). I can't imagine too many small/fuel efficient cars that would be big enough to put 3 car seats into. My wife suggested (ugh) a minivan. I have only owned the Yaris for 2 1/2 years, and hate to even think about how it just recently finished depreciating. I'm pretty broke as of late, and can't really afford a 2nd or more expensive car.

I'd almost be interested in seeing if i could find some who could weld up a steel frame which replaces the back seat and would allow some sort of 2+1 seating for car seats, if i could trust the safety of such a setup. Even if i did feel it was safe, I'm not sure if my wife would agree to it.

Any one have any ideas? It seems like such a waste to sell it...
