It's a long and convoluted story but what was a German coachbuilder (manufacturer of automobile bodies for among others, Porsche) named Reutter was bought by Porsche many years ago, the seatmaking division went through several incarnations until it became a RECARO.

So all Porsches do not necessarily have RECARO seats, and even if the sport-seats in a particular Porsche are manufactured by RECARO they wouldn't necessarily be comparable to the RECARO Orthopaed (spelling??) seats that I'd think you'd be interested in. I was thinking that since Porsche fans are, frankly, even more fanatical than Volvo fans, more likely to modify their car with sports seats snd that PARCARS would likely have some consignment cars around with the seats already installed. If not he'd be more likely to have seats of interest to you in his stock than your friendly RECARO dealer in Burlington.

RECAROs do tend to be featured in sports model Volkswagen, exactly which I can't tell you but, various special editions of the Jetta, GTi and New Beetle turbos have featured RECARO sports seats (I think). Probably easier than finding them in a Porsche in Vermont.

Not to advise you to consider a VW instead but they've had side airbags for years and are at least halfway seious about safety.

Sacrificing the side airbags worries me.

As has also been suggested you might try some other Volvo models and see if you can tolerate the seats in them. I did pay attention to the clearance between my own head and the headrest of my '98 V70 this morning, there seems plenty of space. I did say my wife does hate the seats, though.
