It's a bit hard to use my car as a benchmark for how the suede will behave in a daily, as it spends most of its time under a car cover in the garage.
That said - the first suede wrap job he did, there was a quality problem with the glue he was using and on a hot day when it was parked outside a workshop for most of the day in the sun, the glue let go and the suede started lifting. The suede itself didn't fade or go funny.
He redid the wrap job (and used a glue without quality problems!) and sofar the suede is holding up well. I've had a couple of really hot days at the track where the car has sat in the sun for about an hour at a time and have had no further problems. I do leave the windows down so the heat won't build up in the interior like a furnace! but I guess that's something that can't really be done in a daily that's parked and left for long periods at a time.
Drawing from my automotive engineering experience - it is usually hard to get a material like suede to withstand the UV exposure it will see when in a highly visible area like the dash panel or doortrim uppers without fading very quickly. This is why in most OEM cars that use suede, it's usually placed in low areas of the interior out of direct sunlight so it will survive the life of the car.
I knew all this when I opted to have my dash suede wrapped as I figured it wouldn't see the usual exposure to UV that a daily driver would.
