I still have and use an R65 I bought 2 1/2 years ago. Bought it for middle child to use for a few months, and then youngest went into it at 4 days old. I do have 2 covers for it, I bought the grey R80 cover and infant padding off of the swap here, and then I have the Champagne cover it came with.
I really don't plan on upgrading, the main reason I bought the seat was the longevity I can get from it. And since youngest is now almost 2, and only 22lbs, he's not anywhere close to outgrowing the 35lb rf'ing weight limit, and I doubt he will be by 4(the age I plan to forward face him)
