I don’t believe Probax ever came with the hand pump lumbar support either? Though that could be nonsense… ?
I think Probax came in around the time the LED rear lights and DBW throttle came in.
No idea what that makes yours worth, but I fear they would be more valuable to just keep hold of and swap back into the car upon sale - if you ever sell it ofc.
£500 plus these days, easily. Billy basic S1 seats are fetching £300+. Set of Probax on eBay at the moment £950. These are a bit steep, seen them sell for £750+
I sold mine late summer last year for just over £500 - Probax ones fetch more… mine also had Exige on them which meant most Elise owners weren’t interested…
Those are exactly the same as the seats that originally came in my 2005 S2 Exige, right down to the upholstery. They are not probax but do have the lumbar pump.
Given the nice carbon effect I’d say they are worth a premium over completely std seats.
