I would say no, but consider the stealth performance for $5k less. I was able to upgrade from my MR to a stealth P for less than what your upgrade will cost, but I had to sell private party. For the me the jump from a MR to a P- was worth no more than $10k, so when the math lined up to where that was possible I jumped on it and have no regrets. I don't think the upgrade would have been worth it for more than that, and I think the value proposition is significantly less when moving from an AWD to a P. Your car now already has the range, AWD and low 4 second 0-60 time, so the only things you're gaining are faster acceleration (cool), higher top speed (seriously who cares?), track mode (again cool but who cares), 20" wheels and low profile tires (suck big time for weight, rolling resistance, likely damage and flat tires), better brakes (who cares if you're not on the track), aluminum pedals and spoiler (who cares). The only advantage I see is the faster acceleration, but your existing car is already fast. The delta between the two options needs to be a lot smaller for it to make sense IMO unless you truly won't notice, miss or care about the cash that it costs to upgrade - and I know there are people who fall into that bucket and that's cool too.
