non expired car seat (Wheaton)

ISO useable convertible car seat. Need to use for next 2-3 yrs
has anyone kids outgrown a rear to front facing car seat like graco forever or milestone models . Brand doesn’t really matter as long as no accidents and non expired. Those Graco models just fits better in smaller spaces. My sons going to be 2 and need rear facing for 1 more year. We have an old expired evenflo from our 8 yr old for him that’s expired and starting to rip.
