Time is the most important ingredient for emergencies; but, for the vast majority of DIYs, you 'find' the time (it's right next to the round Tuit on the dusty garage shelf).
As for the tools ... well ... at worst, they're absolutely free (and, at best, they pay YOU to do the job).
For money (which you didn't mention), OEM parts from our sponsors will cost (roughly) half of what you will pay a mechanic to install same, or equivalent (or even worse) part.
For knowledge (also, which you didn't mention), if I can do it, anyone can! And, even if I can't do it, there is someone here who has done it. Just be someone worth them spending their valuable time to help and they will patiently walk you through every single one of your DIY problems, one by one (ask me how I know).
Now for the details!
The tools are free because the labor to have someone else do the job almost always costs MORE than the tools to do that same job!
So, for example, if a four wheel brake job costs, say, $500 bucks in parts, and you need a bunch of tools to DIY install it (let's just say $200 bucks worth), then you're STILL AHEAD from the stealer (at something like $1000 bucks or more).
Plus, you do a better job; you learn about your car; you do extra cleanup work, you feel better, you're better equipped in emergencies, you're more knowledgeable when buying a new used car, you're more fun at parties, etc.
But, specifically related to the tools, they're quite free. In fact, they PAID YOU $300 in this scenario. And, when you do the brakes the second time, they pay you $500 in this scenario).
So, really, all the tools you want, are free (you never see me shirk from buying the right tools for the job ... just look at all the DIYs I've done and you see brand-new shiny tools in 'em all!).
Most tools are re-used so often, they are a money-making business!
Take the ramps. You can make your own, but, even if you bought super duper deluxe ramps, say, $75, they pay for themselves on the first job. And, it's a payment that keeps on giving. Even if the first job broke even due to initial tool costs, all other jobs amortize the cost of the ramps. Over and over and over again, the cost of the ramps drops to nothing. In fact, the ramps begin to pay for themselves on the second, and third, and fourth, and fifth job. WARNING: You have a BMW. There WILL BE a 2nd, 3rd, 4th ... nth. job. Trust me on that. The tools will be re-used!
If you read any of my DIYs, you'll see that I always bought the tools I needed. Just for starters, look at this brake thread:
- A user's very first complete 4-wheel brake DIY experience on the BMW E39 (1)
Not only was this my first post on Bimmerfest, but it was my first brake job in my life. You'll see shiny new torque wrenches, micrometers, dial gauges, disc-brake spreaders, and even an entire set of shiny socket allen wrenches (all I needed was the 7mm size but they don't sell just one). They were all free!
And look at this alternator thread:
- One users' example of total electrical failure (AAA towed away) alternator repair (1) (2)
Again, it was my first alternator repair in my life. I wish I had thought ahead and stockpiled the rebuild parts but this was an emergency. Luckily, I was planning ahead on a cooling system overhaul so you'll see a shiny new chrome steel 32mm wrench and a matching clutch counterhold tool, which not only was free for the belt-drive overhaul, but which paid for itself again when I subsequently did a cooling system overhaul two months later (in yet another roadside emergency where I had the parts stockpiled in my garage forewarned by the Bimmerfest team!).
And, most embarrassingly, just take a gander at my example of the world's worst oil changes:
- How not to do a gravity feed oil change (1) and how not to do a vacuum extraction oil change (1)
For the gravity-feed oil change, I busted a bolt. I thought I would die. If there was one time I wished to write a thread titled "HELP!", this was it. However, I resisted that urge and simply asked for advice. The team here instantly walked me through every step of the solution, folks like cn90 even drawing diagrams of Archimedes'like home-made bolt-removal tools! A friend the next day gave me a ride to the stealer. Ten dollars later I had a new bolt (everything is expensive at the stealer and the San Jose stealer is arguably the worst price-wise in the country!). Another fifteen dollars later, I had an entire shiny new set of variously sized bolt extractors. The old broken bolt was out in seconds; the shiny new bolt back in seconds (and a lesson-learned feather in my cap).
Even with the additional $25 incremental costs + $20 for lunch for my friend schlepping me about, I was still way ahead of an oil change at a mechanic (although certainly not if you count 'time').
Likewise, for the vacuum extraction oil change (although I bought the Motive based on favorable reviews on bimmerfest which, in my experience, were dead wrong. The Motive oil extractor is the worst vacuum extraction tool on the planet.
- Why I don't recommend the Motive vacuum oil extractor (1)
But, it still did my oil change for me. And, I used it just yesterday in a subsequent oil change with a case of Costco fully synthetic motor oil and a better filter (people convinced me to stop using the $20 STP filter in favor of the better $5 Mann filter).
The point is I had never done brakes or alternators or vacuum extraction in my entire life. Like you, I didn't have the right tools. But, I simply bought them. I made some mistakes (more than most); but the overall net is hugely positive in costs. The tools ARE free! I am GLAD I bought every one of them (and the toolbox drawers they go inside). Everyone buys their own tools. It's like having your own dog. It's just something you keep by your side every day. It's the gift that keeps on giving.
If you (insist?) on not buying the tools (which are, as I said, free), then you will NEVER DIY.
Time ...
TIME, on the other hand, isn't as easily solved as tools (time is never free), not even for this lengthy missive. But, time is, for non emergency things, generally allocated on weekends. Weekends are (supposed to be) free!
So, my only sympathy for you remains only on TIME for EMERGENCY repairs. For that, you are stuck with going to a professional (but even then, you never need to go to the stealer).
But, you can avoid most emergencies with a good timely DIY!
So, we're back to the DIY.
BTW, I absolutely HATE to waste effort! Since this is a private PM, I will NOT let out where it came from, but I will cut and paste this into a new thread to point others to.
We really should carry this conversation on in public so that others benefit and add to the tribal knowledge and nobody wastes their time on just one person.
