I got the black because it was included and thought about both your points.
1) keep it clean, yeah that’s out the window. Especially on the frunk because of how you have to close it you get fingerprints all over.
2) the heat part is taken care of by pre-cooling your car or turning on the setting to prevent it from overheating in the cabin.
I overcame number 1 by figuring out I can pick any color under the rainbow and it would be really cheap to apply a wrap on the car. You can get enough wrap of any color for about $300-$500. This means for the cost of the red I could have wrapped my car into 5 different colors. Also, if there’s is any damage to the wrap you can redo just that one panel and not worry about matching the color of the faded panels because the wrap doesn’t fade.
I found some videos of people wrapping their cars and it seems pretty straightforward, I wrapped my center console the night I got the car, so I figured it would be a fun project and won’t harm the car at all so I get to have fun, pick a crazy color for the car if I want, and if it doesn’t work out I’m only out a few hundred bucks.
Obviously your choices are your own, this is my thinkingnon why I went with Black. Good choice on the pearl though, I love that color.
