[My S1]

I'm with Richard 48Y.  Snag that CA S1 ASAP and use the useful parts from the S2 to get the S1 back on the road as it deserves.  Just my humble opinion

That S1 has Most of the tail lamps intact, a Title, and even a 5-speed transmission.
Chassis is unknown but maybe the seller can tell more.
Still needs an engine, which the crashed car can provide.
Sell S2 specific parts to recoup some expense.
Sell the 5-speed from the S1 to recover more.
End up with a mostly correct S1 for the win.

Richard 48Y hit the nail on the head.  Snap up that early S1 on facebook before someone else gets wise to it.  Use the parts from the salvage car and get the S1 back on the road as it fully deserves.  Just my humble opinion...

That blue body on *bay has been on * bay for about six years now. Way back he was trying to sell it for $8k.  His relisting fees must cost more than the car by now.. If you wait another six years it may still be on *Bay for $2500.
