2021 Avalon XSE Hybrid
+1I don't know why you come here to ask about an Accord, but i think for someone 6'4", both will be a bit tight, but i think you have more head room front and back in a Camry, they really made the lines sleeker in the Honda, which personally i don't care for but i am only 5' 8" so either car i would be comfortable in.
I didn't notice the 6'4" comment.
I had no problem with my '16 Corolla or '21 Avalon.
Our pool vehicles at work are mostly Civics.
I hate the things.
They're OK once I'm in, but there's something about the roof line that always causes me to whack my head getting into them, and if it's a tight parking space, forget it.... I can't get in or out.
It feels like they sit lower to the ground than the Toyotas, which makes getting in much more difficult for a larger person.
