The one thing I would say is figure out what you want -- and then own it. If you're a car guy, then buy a fun car because it's a completely frivolous thing that you're going to enjoy the hell out of -- just don't tell yourself that it's an "investment." If you like Disney and want to buy a timeshare, then buy a damn timeshare because you want an excuse to go to Disney all the time -- but don't tell yourself that it's "saving" money to spend less than sticker price ("I could have spent twice as much!" is not particularly compelling), when getting "value" out of that purchase means taking a bunch of expensive vacations that you otherwise wouldn't be taking (unless the timeshare come with free theme park tickets and food for life, in which case please tell me who to call). And most of all: don't kid yourself into thinking you can afford all those frivolities if you have any outstanding debt besides your mortgage.
The thing is, you don't have to please anyone but you and your wife. If you're happy working until you're 57 or 62 and want to live it up in the meantime, go for it -- you make plenty of money, and you don't have to justify those choices to me or anyone else here. Just be completely honest with yourself about that choice: I make a lot of money; I like living my current lifestyle; I am satisfied with my current 30% savings rate; I know that means I will need to work longer than if I increased my savings, and I am fine with that choice. That's where the power is -- figuring out what you want out of life and just going after it.
OTOH, if you're here because you're finding that your current lifestyle isn't in fact making you happy, there are a bunch of people here who can give tons of advice on ways to cut back to a simpler lifestyle. But really, you already know where to start, right? It's kinda obvious. So if what you're really looking for is a pat on the back, that you can have four(!) cars and Disney and debt and a 30% savings rate and still be a Mustachian badass, that's not what folks here are going to tell you -- it's definitely badass as far as the general public goes, but this is a different crowd.* So you just need to figure out which side of the fence you want to be on; you can't expect folks here to smile and nod and say you're doing great when you bought a fourth(!) car instead of paying off the solar loan.
*FWIW, I'm at 45-50%, and I'm not remotely near badass territory. And I also have a royally stupid car that I enjoy the hell out of, so I totally get that pull; I just waited until I was FI to buy it.
