1969 Mercedes-Benz W109 300SEL 6.3 6.3 fuel injected
A truly great classic I am on my second example after experimenting with other cars in the interim
Rebuilt air suspension, new heads, new suspension, new differential many other components have also been replaced.
The Mercedes 6.3 is an extraordinary machine for its era. It is a very rewarding car for the driver and with an an uprated suspension will handle very well. Fuel is not a significant cost as the cars can be relatively economical. The cost of parts and proper maintenance can be significant however the vehicle is far more reliable than even an excellent Rover or Jaguar series 111 which I have also owned.
Would you buy another car from this manufacturer? Yes

Eh, economical? I've owned one of these myself, and economical is not the word that best describes the 6.3 litre V8, but quite frankly, no owner of an m100 Mercedes care much about the fuel consumption either, as these cars are owned by enthusiasts who enjoy the driving experience.
Besides, the car handles very well with the original air suspension, but they are prone to get problems over the years. If the suspension is in good condition, it provides a great balance between good handling and comfort, that is quite unique in cars, and particularly for the era. It always amazed me how well balanced it was and how well it handled, particularly for such a big car, made in 1970.
And of course, the engines are very reliable as well. The m-100 V8 is rock solid and doesn't require much maintenance for such a high performance car of the 60's/70's. Besides, it's strikingly smooth for such a big V8.

I've owned one of these for 6 years now, going on 7, and I agree with the statement of the car being economical - in relative terms. Forget Hondas etc, but compare the 6.3L V8 to the Jag XK 4.2 straight six, and note how much more economical the big V8 is.
