Hmm, I could afford it (maybe, TSLA has been crushed so I couldn't as it stands), but the opportunity cost of $12,000 is pretty big (the differential if you want 19" tires).Yes. Get the performance if the finances are not a problem. If you're going to keep this car for 10 years or so then you'll probably wish you had gotten it at some point. 19" wheels makes sense it that's what you want.
For $12000 the wife and I could renovate the kitchen, put in hardwood floors, take a vacation to New Zealand, etc. Will the perf, even over 10 years, really match some of that? I just don't know. I've said before, at $8500 (the differential if you want 21" tires) I'd probably go for it. At $12000, I'm feeling like there are more enjoyable things to do with that money. I'm undecided.
