I'm debating getting a Y at the end of the month to take advantage of the 7500 tax credit. I'm debating a P vs LR, the 3K cost difference doesn't matter to me but the range difference and the 21" wheels do. In the case of the 21" wheels I'm willing to put out additional money and get T Sportline 19" with new tires. What I want to know is if a P has a mode, chill maybe, that would enable it to match the range of the LR?
