And for $500 a month, pretty much for the rest of your life,  all you 
get is a succession of electronic toys that may or may not last as long 
as the payments.    The Smoke WILL come out.  The only question is WHEN?

Yep. The average new car payment is over $500 a month. That will buy a LOT of 
parts (and labor, if needed).

I'm guessing I did cross it in 1968.   I recently sar a program about it 
on WPTV.   THe cables rusted in the conduits. Snap, snap, etc. then BoooM!

Re: [MBZ] Clean 300TD on BAT

[Karl Wittnebel via Mercedes]

I just put a rebuilt 500e subframe into the 87 wagon. Everything OE except
the toe links, which are nla. New half shafts from cvj reman are over $400 plus
shipping. Parts for the links and new control arms are way over 600. New
fasteners, axle nuts, subframe mounts, lower ball joints for the carrier,
plus a $120 tool to press them in and out, a subframe mount tool, and a
diff mount bushing removal set. New socket for axle nuts. New female torx
socket set for the diff flange bolts. New diff mount bolts and lock nuts.
New sportline springs and spring pads are hundreds of dollars. Swaybar
links. The original sls shocks were done - bad ball joints at the bottom
and leaking; they were about 1300 for the parts alone. I had previously put
rebuilt aluminum brembo 500e front and 300mm 600sl rear vented calipers,
rotors, brake lines and r4 pads on, which was must have been $1000 in the
end without labor, including new master cyl, brake fluid, brake bleeder,
dual diaphragm booster, etc. No more than the rebuilt OE stuff, actually,
in terms of price.
I even got OE diff mounts from overseas as they are backordered for the v8
cars. Rear wheel bearings had already been done thankfully, so I didnt have
to buy that tool or tackle the job, but I would have if they had not been
done. Necessary? For peace of mind, yes. What is that worth?

OE door seals for the car are over a grand alone.

Multifunction stalk switch. Ignition tumbler. Over 100 each oe, excluding
labor.

New headlights (old plastic housing tabs had broken off), magnetti marelli,
euro style, 450.  No labor included.

New dash was $250 and a lot of labor, with all the hvac pods at hundreds of
dollars, new climate control unit, evap, compressor, dryer, hoses.

Swapped a black leather interior in; 800 for the donor 95 wagon. Imagine
paying that labor in DC or any other major city.

You can argue that none of it needed to be done, but when the subframe
starts banging on the underside of the car taking off from stoplights, and
the ball joints on the shocks are creaking, it is time. And after pulling
the subframe out, there is no way I am putting it back with any old stuff
on it. I am not driving a car with a cracked dash, creaky suspension or a
subframe that provides automatic 4 wheel steering. The ignition tumbler has
to work well, the brakes have to be brakey, and it should steer like new.

This doesnt include the 500sl junkyard diff and side bearings and seals,
plus labor. I swapped a wavetrac lsd carrier in, which was over a grand for
the part. I was quoted 2700 for that job alone from Leistung. That's why it
happened on my bench. My old diff was spewing metal fragments into the
fluid and had far too much play. It was also 185mm rather than 210.

Anyway for the 123 mentioned, the axle shafts, rebuilt steering box, and
nla sls struts weren't mentioned. And the tranny sounded kind of hinky.

I am at a point where I sort of want things maintained like a certified
aircraft. I am not driving them and waiting for something to fail. If you
want new car type performance, a lot of stuff has to be made new. For the
daily drivers, I pay someone to do it. For the hobby cars I tackle it as
time allows.

Yes, IIRC. Post tensioning, however, has been used for many years with

Yes, IIRC. Post tensioning, however, has been used for many years with
very successful results.

Re: [MBZ] OT - Concrete Slab Construction

[Allan Streib via Mercedes]

I'm no expert but in the all the construction I've seen, all plumbing
for sprinklers, domestic water, and sewer is installed below the slab.

My thought was that it's for cooling the poured concrete to get a
slower/stronger cure.

I agree -- ask someone on the site.

Re: [MBZ] Clean 300TD on BAT

[Curt Raymond via Mercedes]

 Oh man, for the multi-link suspensions I totally agree. Used ta be cheaper to 
buy all the links at once too.
My last MB Indy preferred to fix things as they broke, felt weird to have to 
make him do it all at once. Maybe he got more $$ in labor doing them one at a 
time.

 Having done the 124 300D rear subframe piecemeal, several times, I have 
to agree with Jaime.  I did the rear of the 81 240D all at once.  That 
is a FAR superior way to do it.   In the end, the last 2 times I did the 
rear of 124s, I did it all at once.   I won't do piecemeal anymore, 
unless it is a short term emergency.

Re: [MBZ] OT - Concrete Slab Construction

They could be doing an exposed manifold  at the ends.

Nope. If you look closely, it’s not a loop or interconnected. The tubing is 
laid out in straight lines and in a grid arrangement, but it just ends up at 
the edge of the slab.

No need for floor heating in Florida. And the deck you see in the picture is 
for a parking garage.
