First the Mustachian Credo forbids this greatly. It's like asking permission to embezzle funds on a forum about Ethics, you'll get little or no opinions. Second, the Mustachian Police will vilify anyone who does not support that credo.
Having said that, I personally think that once you cover the bases, ALL the bases and all the basics, there is nothing wrong with buying luxury items as long as they bring happiness. Don't confuse happiness (long term) with pleasure (temporary). To me Mustachianism is not about being a miser or only shopping at Thrift Shops and borrowing tools from your neighbors. To me it is about being balanced, being frugal and enjoying life.
You need to define what your basics are. Is it owning a home, is it having no credit card debt, are you saving for retirement and other short and long term goals, do you have proper life insurance to cover your family, etc etc. Only you can define what those things are and be responsible and truthful about it. Once all those things are addressed and you know that by proceeding with this purchase you are not going to burden your family/budget/plans/goals, then by all means get it. If the purchase throws you off, then you are not balanced and it's not a balanced purchase.
Two years ago I replaced my car, I posted the question on this forum and was trashed for it, told that I was looking for justification to proceed. That taught me a valuable lesson that 3 years later, I'm able to see clearly. But instead of trashing you I'd advise you to look at your goals and look at your life in general, and then make the right decision.
After all, what is the point of working like a dog, saving every penny and NOT being able to enjoy some things. Some will say the point is about retiring early but I disagree with that. During a fire or while swimming, you are careful how you breath, but you don't fully stop breathing because doing so will cause you to die. Replace breathing with spending and just be careful and be sincere.
