I think you may be able to fit the Marathon, Radian + Snugride together ... not sure which combination, but worse comes to worse your oldest could use a Ride Safer Travel Vest in the center.

You will definitely need to replace the Regent with something, though! Even a Kid-Y harness by Safety in Motion - E-Z-ON Products, Inc. of Florida with a dedicated booster could work (contact that company's customer service for information: they're generally very informative about compatability with various vehicles, etc)

	Booster Seat A booster seat raises your child up so that the car's lap and shoulder belts fit correctly. The lap belt should fall across the upper thighs. The shoulder belt should go across the middle of the shoulder and chest. A booster seat is used for older children up to about 80 pounds. Some states have passed laws requiring booster seats for children up to age 8 or 80 pounds. Check your state's law. Ready to buy a Booster Seat? Please support our sponsor!

	Britax Marathon - Click for more info Increasing the time a child can safely stay in their convertible car seat is a big issue and Britax engineers have come through in a big way with the introduction of the Britax Marathon with LATCH. A LATCH Compatible Convertible Child Seat, the Britax Marathon can be used rear facing 5 to 33 pounds and forward facing from 20 to 65 pounds. Compare the numbers and you will see it is hard to find a seat with these weight limits that is safe and functional. Ready to buy a Britax Marathon? Please support our sponsor!

	Sunshine Kids Radian 80 or 65 - Click for more info If "the Sunshine Kid's Radian 80 convertible car seat is (probably) the only car seat you will ever need," the "probably" part of this statement comes into play when you directly compare the Radian 80 with the Britax Regent. While the Radian 80 has a very high weight capacity, the seat width is only 10" vs. the Regent's 14" seat. The Britax Regent may be a bit wider, but it is very bulky, is only forward facing, and does not fold like the Radian 80. Because the Radian 80 is so narrow, you can potentially put three of them side by side in the back seat. Three Regents side by side? Impossible.
