Oliver,
You obviously have 1200+ posts so are not a new, yet you talk like a typical 220 owner. Speaking
Like as Someone who has taken His car completely apart and put it back together And also as a previous 211 owner, I can tell you that these cars are not the same. I can tell they are made by the same company yes, but not the same cars. The 126's are the LAST Mercedes that you can work on yourself with minimal specialized tools.
I bought my car from a local Indy here in Lancaster that HAS the MB StarTech Computer that plugs into your car and talks to it. I spent 5 months (and 25 grand) in a Hot ass garage here in the Mojave Desert last summer restoring my car to showroom. I did not start out on this car to do that, but it happened. I only meant to freshen the paint and interior and have something to play with. Once I got the car apart for paint, and saw what It could become, I fell more and more in love with it and in restoring her to showroom, or at least as close as I could get it.
When I was doing it, I, having multiple Engineering degrees, wanted all of the things that I had in my "Modern" cars. (On a side note, I bought a NEW E350 and in the first six months had to have the computer replaced THREE times and alsmost filed a Lemon Law Complaint... Three tows from Lancaster to the Valley 60 miles... Three rental cars... What a pain in the ass that was.. GLAD the Ex got it... Ha ha on her...)
I wanted DVD/NAV/Sat radio... Back up camera's... All the James Bond Toys that I could design and build into her. Power, not signal cable is what I ran, and I only ran ONE extra power cable. I am a EE and a CS Engineer, so these were easy...
Was the whole project easy? HELL NO... Were there plenty of moments where someone should have grabbed me and said "Put the checkbook down and step away from the Mercedes"... ?? Hell YES! But as my good friend 48HP says "AMG is a POWERFUL drug" It wasn't even an AMG then, but it is well on it's way now.
Bottom line is that now, after 35K + and 9 months working on it, I have a show piece. One that
I built, with my hands, brains and heart. One that can still be worked on by any guy with a Craftsman tool set like mine. Nothing fancy.. No signal decoders.
Being a Computer Engineer now for 30+ years, I have seen car electronics come a long way. Your car and pretty much all MB from the W140 UP can ONLY be diagnosed with the SDS. As for what 20+ years will do to your car, YOU still would not be able to work on it and will be paying someone else to do it. And you will always be paying someone.
Everyday, Everywhere I go, people come up to me and say "What a Beautiful Car" and I reply "Thank You, I did it Myself". I have a unique sense of pride that one cannot get by simply writing a check to someone for something. Even if Barry Taylor were to come up to me and say "Michael, I will build youanything you want for $XX.XXXX Dollars" I would say, "Only if I can help, even if it is only to hand you tools". Once I locate and drop in a AMG DOHC 6.0L 32V 375HP Engine, I will have one of the most rare cars in the Benz Lexicon. Make no mistake, the people that know me will ell you I will, and soon. But know this, I will have done it myself, and NO AMOUNT of money will ever take this car. None. Literally, My Blood, Sweat & Tears have gone into this car. I could NOT have done it on a W140 SEC XXX or a CL500/600. NOT POSSIBLE... IMHO it could only be done on a Post 92 MB.
We now live in a Disposable Culture. That is what has changed. Mercedes has changed with it, that's why their quality has, self-admittedly, gone down. Mercedes recently apologized for this and has said it is going back to the "Old Ways". Maybe they will simplify the wiring? Who knows.
This is the 126 Forum. More of a DIY forum than a "Yeah, I got a new Yacht" Forum like on the 220/221 boards. I really can't see much of a "How do I?" going on there. Maybe I am wrong, I spend no time there.
But here we try to help each other restore these cars to their former glory. The manuals are available here and there are people that know them and these cars and are willing to help the newbies. I have been on both ends of this and I often still am. I post DIY's and I ask for help when I need it. I always give it and usually get it back in spades. You can laugh at our "Quaint Antiques" but we like them. And we love them. We are a big family here on the 126 forum. We fight and we laugh, but we help each other.
I couldn't possibly imagine what you people over on the 220/221 boards talk about? Who the best Mechanic in town is to give your money? What then?
I loved that recent post by 48HP about his fantastic save of that GORGEOUS 500 SEL AMG. That car was one step away from the crusher... He has not told me, nor do I have any knowledge of how much he paid for it and restoring it, but if it's 20K it's a steal.... One of the few "REAL MADE BY AMG IN AFFALTERBACH HE HAS THE DOCUMENTATION TO PROVE IT" cars on the road, and he saved it from the strippers... Bravo.... I want
MY sedan to look like that...
Even Charlie's 84 Euro SEC. He saved that car from the crusher and has done all of his own work (mostly) to restore it. Bit by bit, part by part. Now he has a very clean rare Euro coupe. Nothing fancy per se, but a rare clean coupe nonetheless. One beat away from the crusher, now on the road, all by himself.
Ain't gonna happen with your 220/221's... Too complex... Too expensive... They will go the way of the Do Do Bird... Ours will still be driving.... Cuz we love em and will fix em... To use the vernacular...
Just my thoughts...
Ditto on the Lawyer...
