I am parking the XC90 in an underground garage along with many other cars. I am concerned that exhausts from other cars and dirt in general will leave oily residue on my new car and want to cover it with a full car cover. At the Volvo dealer today, they told me Volvo doesn't make a cover for the XC90. Does anyone know or used a cover that works with XC90? Also, in practice, is it OK to put the cover on right after turning off the car while the engine is still hot? or should I wait til it cools down then put it on? Also, will the full cover obstruct any active/passive security system within the car? Thanks for any info!
