i simply have no need to blow $$$ on tools and such since i drive newer cars that i get more miles out of without fixing.
i have no desire to waste my spare time fixing a car. i'd rather be doing something with my girl and my wife. i have no desire to hunt for parts, shop supplies, workable tools and keeping them organized, and my garage is not heated. the lighting is totally inadequate and trouble lights suck. i don't have enough room in my garage to work on anything. i have no desire to clutter it up with more tools than just some basic tools to upkeep my house. tools and tool cabinets cost money. and i don't enjoy taking apart cars. I watched my dad (who was a diesel mechanic for 20 years by the way) overhaul and work on all the family cars over the years. i helped him sometimes. engine work, brake jobs, body work (that really sucks) taking cars into the tranny shop....and the list goes on and on.
my car expenses are much more predictable and easier to budget for by getting a newer rig mostly in warranty and getting the best most trouble free miles out of the car. One time a bought a 7 year old car and it turned into a bit of a money pit. instead of the 2 or 300 a month for a trouble free ride, it was just pumping money into the system of mechanics. Would i have benefit by doing any of the work myself? Some, sure. not enough to offset the time and hassle and money it would have taken me to acquire all the tools and parts and not to mention that my townhome association didn't allow folks to be mechanics out of their own small 18x18 garage. you forget, almost no one has a pole barn with extra space to do that stuff.
What's a nice air wrench and compressor cost?
that would make a few car payments.
need any special tools for that brake job?
and then when you're talking trannies and clutches and stuff, and front end work, you're likely not gonna do that work yourself anyways.
basic maintenance work like rad flushes and tranny flushes are cheap and infrequent. nobody puts their own tires on. and VIOC will change my oil, on my whim, in about 15 minutes, and i can get that done on my way into work on any given day. i don't have to plan part of a saturday for it.
had a wheel bearing replaced on my aztek a few weeks ago under warranty. had i needed to do that myself it would have consumed too much of my time. i was in and out of the dealer in about 60 minutes.
like i said, like 99% of the folks out there, i prefer to get my work done, and that's why its of more benefit to me the owner or user of the car to return the space to the cab where its much more useful than the once a year someone might have to get to something under my hood.
I've had a pretty good track record with my cars overall. Most of them that i bought which were new or newer I've done mostly just oil changes, tire rotations, flushes etc. too. Some of my cars I have not had to spend more than a few dollars to have others do work over the time I've owned the car. The only money I put into my 95 tbird for repairs in 71, 000 owned miles was a battery. no brakes, tires (other than snows) or tuneups or anything. I had something taken care of under warranty (windshield leak) that i wasn't gonna do myself. i owned my tbird over 4 years and aside from oil changes i paid 80 bucks for a battery. And that's right under the hood.
