Hey guys, I am not sure where to look for option codes online, so I figured I might as well post here first, and if not, I'll move to the 968 section. ANYWAY.... can someone decode these options for me in this listing?
Thanks

454 Automatic speed control<---- cruise control?
650 Sunroof
718 ???? its not listed!
220 Limited slip differential <--- what is the difference between this and "Porsche locking differential"
331 AM/FM cassette with 2 door speakers
423 Cassette container and coin box
425 Rear window wiper

 

does anyone know what the option codes 454 and 718 are?

 

454 = big block american v8 option

 

if only

454 is cruise control.

 

718 is a "model code designation"; it's actually pretty common on 968's, especially the later ones. It has to do with production of that car starting one model year, but for whatever reason, the car wasn't completed untill the next, so the VIN number was changed to the newer model year.
454 is the cruise control.

 

718 option code means the car was a carry over from the 94MY and then was given a new VIN for the 95MY.

 

This is a guess, so don't quote me... but I read that early on, the diifferentials had an 80% lockup (I'm guessing this is the "Porsche locking differential"), which caused some problems with street drivers on lockup - caught them unprepared, I guess.

Porsche subsequently changed it to 40% lockup, which I'm guessing is the "Limited slip differential" - but this is only a guess.
