SL/R129: 99 sl500 top
Even if it doesn't crease the window, it will crease the fabric and greatly increase the chance of it splitting next time you raise the top.
A cat has rewarded me with rabbit entrails on the driver seat, A helper dropped a fire extinguisher, the leaf vac/blower did! etc
In Kansas I keep the top down for nice drives year round. The hard top goes on for visits to the mechanic and multi day drives because the wife of 52 years hates the open car ( a way to escape for day trips! )
I have replaced three back windows ( in 3 different R 129's ) but the reason was first the brown discoloration.
When the soft top is moved I make sure the vehicle and air temp is warm. ( warm outside or heated space before hitting the button! ) the cold weather move has split the plastic every time.
And as mentioned by SRHsl600, before you even operate the top, you will want the car to be in a warm environment for a few hours.
