I've been trying to pay attention to how fast my NSX warms up. My car is garage kept so it does stay about 15 degrees warmer than the outside temp.
I also have concerns that the car is taking too long to warm up. 15 minutes into my drive today (about 35 degrees F) and the water needle was still on the lowest hash mark!!! About 25 minutes into the drive the needle was in the middle but if I turn the heat on the needle drops again.
Is this doing damage to the engine? I always heard that warming the car up in the driveway is not always recommended, I usually only sit for a minute before I start my commute. Should I let the car warm up more before I leave???
