If you are talking about the Evenflo TRIUMPH ADVANCE, then you are looking at a great seat. AS for the Evenflo TRIUMPH...eh--super short shell and will likely be outgrown VERY early.

I have found that the Evenflo Triumph Advance is slightly taller than the Marathon, BUT it will only hold to 50lbs vs the MA's 65lbs. The TA will RF to 35lbs and FF to 50lbs. The Marathon will RF to 33lbs (though they are slowly going to 35lbs) and will FF to 65lbs.

They will all likely fit very well in your vehicle b/c you won't have to have that full 45 degree recline that newborns must have (unless she has a medical condition that will not allow her to be inclined). She can be inclined between 30-45 degrees and as long as her head isn't flopping forward when she sleeps, you have the right angle!

	Forward Facing Car Seats A forward-facing car seat is one in which the child sits facing the front of the car. The seat should be installed in the back seat of your vehicle. Most forward-facing only seats are for children above 20 pounds.

	Rear Facing Car Seats A rear-facing seat is one in which the infant faces the back of the car. Always install a rear-facing seat in the back seat of your car. This is the safest position for an infant. NEVER place a rear-facing seat in the front seat of a vehicle with passenger airbags.

	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.
