I purchased this seat with intentions of using it on the passenger's side of my Boxster, but it turns out that it won't fit due to how the roll cage came out. Not sure if it would fit on the driver's side or not, but I suspect it would. Brand new, good until 2021 - will get a picture of the date stamp when I get it back from the shop on Monday.
Details and sizing
here...it's a big seat, that's for sure
$409 + shipping new, I'm asking $350...really don't want to ship it, so somewhat local to Philly/Baltimore is much preferred.
