I'm not going to judge this, one way or the other, because I can see it from both sides. You have to do what makes you happy, while still being responsible. Personally, I had a cheap-paid-off car, bought my current house, then got the MS3. BUT...with my last house, I had someone refinance my car beforehand so it didn't show up on my credit report. I ended up making almost $20k a year later when I sold the house, and had the car i wanted (and couldn't technically afford) the entire time. Basically, a text-book example of the wrong way to things.
There is no universally "right way to do it"...it depends on the person.
Just my 2...
Exactly! What works for person A isn't always what's going to work for person B, etc.
