I'm a newbie and this is my first post, so apologies if this is posted in the wrong forum section. I ordered my Model S yesterday. Tech package, pano roof, leather seats were the only options I chose since I'm trying to keep price manageable. I didn't get the upgraded stereo but am kind of second-guessing that. How important is it? If it were cheaper, I'd definitely spring for it. At $2,500 it's just such a pricey addition. It would help to know how good the standard stereo is. I heard it on the test drive, but didn't turn it up very loud. I'm not a hard-core audiophile or anything, but I do like to crank up the music sometimes and I want it to sound good. Am I making a mistake to go with the standard stereo or is that sufficient for most people? Any input would be a big help!
