I know firsthand that needs and wants change over time. When my wife (well, then-fiancee) started a new job in 2008, for the first time we needed two cars. Up until that point, I had wanted, if we did two cars, to keep the Subaru as the practical car and get something sporty and impractical for the second car. But since my wife had never had a car of her own, it turned into buying a new car for her, so we bought her 2009 Mazda3 hatch, which she loved. Now she had her car, and I was still driving the practical car that I hated (2005 Subaru Outback, 2.5i auto). By fall 2010, I was sick and tired of driving a car every day that I didn't enjoy the driving experience of. The 3 was great, but not roomy enough to be the only car for our needs either.
I ended up buying a 2010 Mazda6, which was a compromise between what I wanted and what could be a reasonable only-car for us if we sold the 3. After months of me dropping her off and picking her up from work 90% of the time, we finally sold the 3 last year and are a one car family. In the meantime, however, she's now bought a horse, and we drive down a gravel road to the barn 3-4 days a week, giving us countless annoying rock chips on our shiny, low-to-the-ground family sedan. If they hadn't been over a year away at the time, I would have held out for a CX-5, even not knowing then we'd be buying the horse. Had I known, I'm not sure what I'd be driving now, but it might not have been the 6.
Anyway, I have a 6 now that I love to drive, but it's still not a sports car, much less a Porsche. My mom is still holding onto her 1977 924 Martini Edition and unwilling to part with it anytime soon. My wife and I are paying down our mortgage (overpaying every two weeks), her student debt, and some of our younger/dumber spending debt, along with a ~$400+/month horse hobby for her. The light at the end of the tunnel of all of this is debt going away and being able to spend money on MY hobby, which would be owning one of the cars above. I needs my dreams, man.
For a transcendent car, I would love a 996 GT3 or a Cayman R. That would mean saving longer before I get to that point though, and I'd rather have a base 996 a year sooner than to wait for something I'm frankly not experienced enough to appreciate the extra capability of. That can come with time. I don't want to try to buy one now and juggle debt, which would be stupid, but I also don't want to wait until I'm 40 and can afford a TCL-Approved 993TT or 996 GT3 RS.
