Looks like we are ordering a MINi. $4k is a pretty big jump to Signature Plus, but I kind of want the moon roof. Logic says it’s not worth it just to look up and see glass. Are there other reasons to get the Plus? Is the interior material that much better? Is the stereo that much better? Will it have better resale? Also, is it better to go with 17” wheels or 16”? We will be driving a lot of Southern California Freeways commuting to work.
