I just found this site and have been devouring the content over the past couple of days. I am mostly Mustachian, I believe; I just never knew the word for it.
Frugality is something I've been practicing for years. I don't believe in having any debt other than the mortgage, and I pay extra principal every month. I have been doing all my own auto maintenance and repair (and being chief mechanic for my parental units) for many years, and I've also been learning a bit of carpentry and plumbing and such.
Everyone has a hobby of some sort, right? It may be anti-mustachian, but if it's pleasurable and not having a huge impact on the goal of FI, it's not all bad.
Mine is automotive. I'm a single guy and I own three antique cars. I paid cash for all of them, and none of them is worth more than two or three grand (and only to the right buyer--niche market). Insurance on them runs only about three hundred a year for all of them. Registration costs are nonexistent; I paid for one-time antique registrations which will last forever. I don't drive them much; I take them for occasional car shows and limited pleasure driving. I enjoy wrenching on them more than driving them, honestly. They only get four to five hundred miles on the entire fleet in a typical year.
So they don't cost me much, and I do enjoy them. One was an absolute dream car that I'd wanted since I was a kid, and I still want to own it. Is there anyone else here with an antique car collection?
