>>14231544 BMW is the only way to go if you want to DIY. It has the best community in the world and you can find information about ANYTHING in the Internets. Mercedes is little bit more reliable in general, but forget about DIY, and repairs also can be more expensive
If I bought a E36 or E46 M3, got the repair manuals and tools and learned to wrench bretty gud, would I still get raped by parts costs when stuff broke, or would it not be noticeably more expensive than a normal car?
I'm good at figuring shit out with manuals and the internet and I'd like to own a cool old luxury car, but I'm wary of it becoming a money pit despite my best efforts.
>>14231544 1999-2006 were the worst years for Mercedes. Before that, Mercedes had floated around 2rd and 4th place amongst Toyota, Lexus, and Acura and in the 1970s to 1980s were even above the Japanese several times brands regarding reliability. When they merged with Chrysler they took on an entirely different mentality that didn't include making their vehicles overly durable regardless of cost and they cut a lot of corners and took shortcuts in their designs to save money. Between 99 and 06 they actually dipped below BMW and were even below Jaguar and Dodge.
After Mercedes split from Chrysler their dependability started to climb back towards the top. This was around 2007-2009 that things started improving. Now Mercedes is back in the higher range regarding dependability. I think they're in fourth place right now.
With BMW the inverse happened. They were more reliable during that time but around 2003, right after the E39 exited production BMW started making their vehicles needlessly complicated, with horrid electronic designs and fragile parts all going towards making their vehicles lighter and more profitable. When the E60 and E65 were reliased those two models alone dropped their reliablity massively. Around 2007-2008 the N63 and N57 begin to be phased in, which were full of issues. BMW has becoming increasingly less reliable since.
From 1980s-1997 Mercedes were more reliable. From 97-03 BMW was more reliable. From 03-06 neither were great. From 07 till present Mercedes has been more reliable.
>>14242777 SLKs are easy to work on because they were built on an already existing W202 platform and were spared much of Daimler-Chryslers dumbfuckery. They're super underrated cars. My first car was a W202 C-Class. Older Mercedes are great.
Also, yeah. Mercedes are only expensive to service if you go to a dealer. A lot of work can be done cheaply if you do it yourself. Longpost guy made a long term ownership chart of the costs of working on his M-Class as opposed to what they dealer would have charged him for the same work. He did everything for about 20% of what the dealership would have charged.
>>14242789 Yes. That's just a basic approximation.
The E36 was far more dependable than the E65, just as the E39 was far better than the E60, but the change in electronics suppliers BMW went through in late 03 (which would be model year 2004 vehicles) was a major source of many problems. 3 series were never particularly problematic until the E90 was introduced which spawned a multitude of issues, especially on I6 models.
>>14231544 BMW has a lot of online info. Probably the most. All mechanical jobs are on youtube. You can even do the computer stuff if you're a bit computer savy - the tools (INPA etc.) are available on torrents and the cable costs $20. Then you can read, reset errors or even do coding for new features or when you put new ECUs in the car. And for BMW there is probably 10x the information more than for the merc on the net.
>>14242829 Both. Problems with everything from lighting and infotainment systems, to ECU, ignition systems and transmission controls.
At this time BMW was trying to become more profitable and they stopped making much of their own stuff and started moving a lot of the supply base away from their historical contractors like Bosch in Germany (and to a lesser extent the US & Mexico) to weird OEM suppliers in Malaysia, China and Slovakia who would were simply contract manufacturers. Similar practices are done with consumer electronics, like iPhones and Playstations which are actually made by Foxconn and Pegatron, not by Apple or Sony.
This led to a lot of quality control issues. On top of that BMW itself started basically cheaping out on parts quality to save money at their Germany suppliers too.
You mean diagnostic? This + a windows XP virtual machine with INPA installed (NCS expert for "coding", winkpf for flashing ECUs, tool32 for more advanced jobs). This works for cars such as e46, e39, e6x, e9x but not for newer I think (F10 etc.). Newer cars have more security and more advanced systems. Here you are basically talking to the car via a COM port.
It is possible to register a battery with this but it's not completely trivial.
