I’m stuck between purchasing the Evenflo Pivot travel system or the Doona Stroller

The Travel system would be bought new.

The Donna Stroller would be bought used.

The lady selling the doona stroller only used it for about 6-7 months. No accidents. She’s selling it for $200 obo

Anyone had experience with either one of these strollers? Would you ever consider buying used?

Of course I want the best for my child, but the Doona stroller is a steal! But I feel conflicted because idk. Should car seats be bought new?
