Which year R129 is the best, least trouble free?
Hi.......... I'm looking to buy an SL R129 body, probably the V8........
Can anyone advise me what is the best year.....or worse to own? What should I look for or look out for when shopping for one?
Thanks

Agree with that. It's worth going for a car after the first face lift in 95/96 (identifiable by the door air bags). It's also correct that full service history is vital. Differences in how the car has been used and maintained will completely mask any year to year variation.

I bought a 99 320 v6 last lear FMBSH 23K on the clock...
So far I have spent about £2000 on the bloody thing
Gearbox leak,
MAF/MAS sensor,
Catalytic Converter,
Paint Work,
now needs new plastic windows in the softtop and the windscreen requires refitting to solve a small leak

It had 2 Services as well in that time... and I have found some rust inside one of the sills...
The SL's are good cars and are genrerally reliable but parts wear out like any other car...
I don't think the service history is the only answer to a reliable car
The problem with the SL is that you are paying new car money for a +6 year old car so expect 6 year old car problems and you won't go wrong...

I think that over all, the R129 is a car that have less problem than other cars from same catagori and year. It is´t for nothing that it´s called "safebox".

The older models seem to be more stable.
I would say the best production years were 1994 (pre-Facelift) and 1998 (last year of Facelift1-Models) - it depends on what you're searching for.

Rust on an _internal_ panel is worrying as it means that water got in to the car somehow so now you are faced with two tasks 1 find the leak 2 fix the rust...
The SL is built so well, most owners would not ever know that the car was rotting inside out in the event of a problem
have you taken your carpets up lately to check for water? I doubt you would find any water unless you did although it can be present in large quantities... The later paintwork sucks (post 98) I regularly see 10 year old cars with better paint than the last facelift models.This with possible rust issues could mean that the older cars are a better choice althought the v6 is certainly nicer than the older straight 6

As for the rear window, as long as it's not cut, I used the MB plastic cutting polish. Brought them up like new!

Have the say the very last morning I had my SL600, I was cleaning it out, vacuuming the carpet behind the drivers seat and it was sodden. Lifted it up, a real mess underneath - so that was the musty smell - and was pleased the car was moving on. No idea how it can have got so damp.

my water was comming in on the passenger side in the same place
I think its something to do with the door seals
its very impressive how well the car hides water though

Hmm, are we talking about same thing? I purchase my SENDER UNIT, AIR-MASS UNIT for 13 EUR

What is that? Do you have the article number. I used MB glass cleaner, and that was crap for plastic windows.

Is there a way to recode the SL key's? I think my neighbour's has lost its code due to low battery...

Yes, You have to order a new key and code it into the computer in the car. You can code 8 keys into the car. What happens after that I don´t know.
EDIT: Ok, He did´t lost it I see now. Lost of batteries should not force recode. However, that could be done if the car have lost the code.

Key re-coding
If you replace the battery in the key holder, then it will lose it's memory for the code. Any mercedes dealer can give you instructions but it is very simple. You stick the key into the ignition and hold down the alarm button at the same time you are turning the ignition over and it should work fine.. May have to do it a few times.
