How to calculate price for carseat


New member
I am wanting to see what I could get out of my Marathons and if its worth it to sell them so I can get the CA65. I have three MAs and love them but the lack of legroom is getting to me and making it hard to get my 20# 2yr old in without a struggle. The mfg dates are 4/2008, 4/2008, 6/2006. I cant remember how to calculate the numbers to see what I should sell them for, I also have three cowmoo covers, one tribecca and a faux paw too that I would sell to fund for two CA65s and maybe a Nauti for my almost 4yr old. TIA

The equation most people use is retail price/years of life x useable years left. My 2007 Marathon would go for about $140.

Yes, this, but also deduct for any stains, snags, etc, and if there's any newer version of the seat out.
