I completely agree, I am giving up on a loosing battle with my 98 Plytmouth Breeze. I am tired of dumping money in to it over and over, it's time to let it go. I should have researched it better before I bought it, cause from my understanding 98 was a BAD BAD BAD year. SO I'm paying out right for a newer car with better ratings and MUCH better gas miliage.
So, I think you're right, sometimes it really does make sense to get that new car.
Also, this thread keeps giving perfect examples that there are exeptions to every rule and that all we can do is intellegently ***** our own financial situations and make a decision for ourselves.
Refinancing my house with a cash out refinance is probably considered dumb by alot of people, my parents especially. . . but it makes perfect sense to me and my husband.
When we bought the house 4 years ago we bought it for $69,000. We had a BOOM in real estate here and this year our house was worth $160,000. We jumped and refinanced, although the interest rate is great for right now, it was higher than our interest rate on our old loan. BUT our old loan was a variable, so it was only going to go higher, and I predict much higher than what we locked in at on our new fixed loan.
We cashed out but left 20% equity to avoid PMI and to leave some equity cause you never know.
We used all the money to pay off all of our debts (which was ALOT), pay off our current car, and we have some set aside to pay off our new car we're getting, and add an extension to the house (which will add more value). We had some "free" money left over -but it will be spent at Disney I'm sure.

Yes, now we have a $1,000 a month mortgage payment, BUT it is less than the $2,000+ a month we were paying on mortgage, credit card minimums, car payments, etc.
I'm not afraid of our house value going down, as we have 2 airforce bases that are not part of the ones being shut down, and are in fact going to be recieving a lot of new air force people from other base closures.
The one thing I asked myself too was, would I buy my house NOW if I was in the market. Yes. And I would have to pay that $160,000 to get it. But since I had bought it much cheaper, I now get the house, a new car, all my debt paid off, and I get to make the house even better with an extension. And I didn't have to magically come up with a 20% down payment. All for the same price I would have to pay to buy it right now.
