Hello-We just bought this 87 (silver/red interior,have a 63 corvette silver/red interior, 98 boxster silver/red interior..kinda fun), SL has no owners manual. We have figured out all the buttons except one. There is a black square button that moves up/down/side to side its located under the gear shift in the middle of the seats. Pls explain. Thank you, its nice to meet you.

 

without stating where the button is I am guessing it adjusts your side view mirror.

 

Hi,
I have one I am debating parting out...
Needs work on the fuel injection system
Have you guys ever had this worked on?
