Following a short break from Merc ownership, I'm now back in the land of the living with an '83 280CE. Before buying it, I was advised to get a post '82 model, (with rev counter and electric n/s mirror) but the person who advised me wasn't sure why. Does anyone know the answer?

On the subject of rev counters, she seems to rev alarmingly high, I know its a short stroke motor, but 4k+ at 90 doesn't help the fuel consumption at all - short of driving more slowly, is there a way this can this be addressed with a taller final drive/axle ratio, or would this just confuse the autobox?

Finally, although the car is faultless (within reason) and low mileage, the interior covers (velour) are beyond repair - the car's lived somewhere hot and they've 'baked' to a fragile crispness. I'd like to replace the interior with a leather one, which seem to be scarce indeed for this model, would a replacement from an SEC or a 124 series CE fit, or alternatively, does anyone have one for sale?

I asked a similar question about the revs on my 280TE but couldn't find out much. I did find out from somewhere that the diesel models of the W123 had longer gearing but it isn't much, it only drops the revs by about 50 or so at 60mph.

Any changes you make after the gearbox will throw the speedo off so you might want to get that recalibrated if possible.

You could try bigger wheels and tyres to get the same effect. The 8 and I think 10 hole merc alloys are available in 16". I worked out that 7 x 16" wheels with 205/65 tyres combined with the diesel diff could lose you 250 revs at 60mph.

It's not much for all the expense but it is something.

Hi

You really should of bought a vehicle 84 onwards with the 4speed auto. Although the rpm will still be high. Nothing can be done. 5sp auto's did not come in for a long time after that.

As for the interior. Only the seat frame is the same as a 126 & then not an SEC. Other than that all the interiors are different.

Thanks for this - if I could get 15 inch alloys in the same pattern as the originals I could be tempted, despite the marginal benefit, but Andy, I thought it was a 4 speed box - the book says it is...!? :shock:

As for the interior, guess I'll have to join the queue
