I purchased a Britax Marathon for my daughter in 2005 after she outgrew almost all 40# weight limit car seats on the market by height at the age of 2 1/2, and have really enjoyed the seat for the 4 1/2 yrs I've had it.

The Push button Latch makes it extremely easy to install, the harness is a breeze to adjust, the seat is plush and comfortable. Rear facing or Forward the seat is great all around and has been used constantly since I bought it and it still looks like new!!

Another perk of the Marathon is lots of cover choice, not important to all but I figured if I was shelling out the money I should...
