Authentic......I was in the same boat as you (Albeit....some different variation) but let me pitch this idea to you. I havent read the ENTIRE thread, but I caught the gist.
It seems (from what I've read) you're still making payments. Best thing you can do is just eliminate that ENTIRELY, depending on what you owe. You'll exponentially increase your cash flow per month and save a lot more. Having an MK6 will undoubtedly net you more money than what MY car is worth, so you might be in a better opportunity to sell the car, pay off what you owe and jump into something "fun" yet cheap. There are plenty of things out there than can offer just that.
Of course, this is easy for me to say since I had my car fully paid for, but you might be able to pull it off. You're already got the right idea by decreasing CASH FLOW instead of huge capital up front.
This. I think about money all the time, and how to save. Not having a car payment would really be benefical. I realized the only way that it was truly worth getting rid of my car, was to outright buy one, or put enough down that payments were 100-150 a month.
