I'm new and would like you all opinion on which to buy
2000 and above is way above my budget
I need ac. Heater not necessary
Thanks

Year 2000 or 2000 dollars?

I'm partial to the W123 chassis myself. They all came with AC AFAIK, but few still have it working. You can get a cheap one for well under $2000 if you look hard.

83 300D Turbo with manual conversion, early W126 vented front rotors and H4 headlights 401,xxx miles
08 Suzuki GSX-R600 M4 Slip-on 26,xxx miles
88 Jaguar XJS V12 94,xxx miles. Work in progress.
99 Mazda Miata 183,xxx miles.

Can you do your own mechanic work ?
If you get a car which needs stuff... the 123 model was the most produced model..
so most places parts cars are available for it.... if you have room... complete parts cars are really helpful on these old relics....

The w123 is a favourite, however is a little antiquated these days. The w124 would be my first suggestion. It's a world above the w123 in terms of creature comforts and ride quality. It is also much easier to find a nice rust free example.

when it comes to newer diesels.I look for at least a cast iron block.I perfer a inline engine too. Mercedes is switching back at least to cast iron.

I loved my 92 w124. My 96 w210 is a serviceable daily. I really regret not reaching for an impeccable 2006 cdi. You can't go wrong with an old w126 either. Have never driven a 123 but still see a few on the road.

Both retired cars are for sale as is my w124 shop inventory

We have a 123 and a 126, both of which are great for different reasons. The SDL, while a bigger car, I find to be peppier and has more throttle response than the 123. The 603 engine's original #14 head had issues which other owners can clarify and provide better context than I, but if well cared for, will last just as long, if not longer than the 617.

You really can't go wrong with either, but my best suggestion is do as much research as you can before you fork over the dough for one. YouTube has some really great videos on there about what to expect for maintenance if you're a first time buyer/owner

I don't know that I would ever go back to daily driving a w123\first gen w126. I decided that I wanted something with airbags which means 2nd gen w126 or w124 or later. With the way that CDI prices are in the US (they are still waaaayyyyy more up here in Canada) I would seriously be looking at one of those. My next choice would probably be a 98 or 99 w210 followed by the w124 2.5turbo as it doesn't have any of teh head issues that the 3.0 had.

Year 2000 above is too much $$$
The 92 to 95 is non turbo
The w123 ac is not efficient and I live in Vegas
The m606 is too risky and I am not a good DIY person
I can manage changing brakes and axles, shocks but not timing belt and valve adjustments
On the 96 to 99 which year to get? 97 and above has 5 speed auto
Is it better overall

My 85 w123 300TDT has an airbag factory...

Both my 85 w123 and my 87 w124 are daily drivers. I like them both for different reasons. If I could only have one it would be the W123. The W124 is faster, gets better MPG, is more comfortable (mines face lifted to a 94 inside and out) Wife likes it better of the too. But there is something about the w123 that just makes me smile every-time I drive it. Also, I see a lot of the w124 out there, but I rairly see another w123 wagon... It also stands out in a parking lot... never loose your car! The w123 is also the car that if I had the fund, I would have fully restored.

Not true, the 300D 2.5 Turbo that was available in that era was a turbo engine.

Everything newer than 1985 has no valve adjustments (hydraulic lifters are self adjusting) and all Mercedes diesels use timing chains that last a good long time.

96-97 is non-turbo om606
98-99 is a turbo om606
and since you said you didn't want a 606 that pretty much rules those out for you.

Given what you've said I think the 2.5 turbo (OM602) would be the best car for you. No head issues like the 603, and no glow plug issues like the 606. The only thing that is a known fault on these is the vacuum pump, which MUST be replaced if it is the original (approx. $300 in parts) as they had a design flaw that could cause the timing chain to snap. Other than that they are bullet proof.

However, with all that being said.... If you are not a DIY kind of person, I would strongly caution you getting into older diesel Mercedes.

Very well said. I have told people that if they didn't like to tinker with a car, old MB diesels would probably not be a good choice.

W.

Your concerns on the OM606 engine are unfounded. These are in the 95-99 E300. 95 was the last year of the 124 chassis. The 96 to 99 are the 210 chassis. This is the last and best IDI engine MB made.

The engine to worry about was the OM603 for 2 different reasons.

The OM603.960, used in the late 80s 300D/TD/SD, have a weak head "#14" that if overheated is pretty much guaranteed to crack.

The OM603.971, used in the early 90s 350SD/S350, suffers from bent rods. However the #22 head is good.

I have a 98 E300D and it has been a solid vehicle. These can be had for the $5-7k range well maintained. I have 228k miles and counting and the only significant issue I have had in the 2-1/2 years and 35k miles has been a front wheel bearing.

Do your homework and research them carefully. I personally recommend either a later series 124 (90+) or the turbo 98-99 210s.

I would personally recommend the 85 SD. Find a good one with no rust and with the problematic cruise control working, new tires, ready to drive. Then you can tinker with it as needed but still start with a good solid car to drive.
Oh, I just happen to have one for sale... can I interest you??
