I would only halfway agree. The 4.5 engines are bullet proof and mine's never given me any problems. What parts I HAVE replaced were easy to find. The 6.3 is another beast - expensive to maintain and parts are harder to find.

I owned a 1972 4.5 and agree on the engine, but the mileage was somewhere around 12 mpg. In California gasoline is approaching $4.90 per gallon. These older models do not like the Etnanol blends with the poor octane ratings. I've had better success with non-ethanol blends in my engines. Mileage improved.

Let's not mislead them - the I6's are pretty thirsty too for the amount of power they make. If fuel economy is your thing, do not buy an old petrol Benz. I think you are best to find the best condition car you can, regardless of an I6 or 3.5/4.5 V8 motor - replacing parts to get a car reliable could cost a lot more than the incremental difference in fuel economy. Rubber weatherstripping or wood repairs could cost quite a lot compared to other brands of car.
Good luck in your search.

K-A: As you might know and as I have read time and time again on this site, buy the most expensive w108 you can afford. Let someone else put in all the restoration costs-because you'll never get them back.
Luckily there are a number of fine W108 examples, especially in CA. Just be aware of the rust issues, which are usually more problematic in the other parts of the country.
I have found that parts are relatively inexpensive and readily available for these cars, it's the labor costs associated with the repairs that will get you.
Finding a well maintained W108 is key. If you can find one with all the maintenance records, that is ideal. There are a number of them out there that have that information, so you don't have to feel "forced" into buying one without.
I use mine as a "daily driver", maybe 5 miles a day, and absolutely love it. It is amazing how much respect this vehicles garnishes. I'm guessing most have no clue how affordable they are; people I know believe I paid $30K+ for the car.
Good luck to you.

I agree with SF W108. Buy the best one you can afford. This is my 3rd year with mine and it is great. I use it almost daily in the summer. Last year I drove it 2200 miles in 8 days on a MA to SC trip. It performed flawlessly. Parts are readily available and not too expensive. Gas mileage for me has been about 14 mpg around town and 17-18 mpg on my long trip. My maintenance costs have been very reasonable. A surprisingly comfortable, driveable car that performs well today and looks like it costs way more than it actually does. Always gets lots of attention.
