The Lancia Zagato Targa Coupe was designed and modified from a coupe by Zagato. The Targa Top could be put into one of four configurations. From 1981-82, 791 units were built of which 75 were Special Edition.
What I came across on Google.
Did they give any hint as to the configurations?
I've had mine in three of the following four but I suspect it's not what was meant in your quoted search result!
1) Behind the front seats
2) In the boot
3) In the garage
4) In the windscreen of the car behind if you forget to secure the locking clamps
