How good are those first mercedes V6 engineS? Engine is beatifully smooth and sounds good. With regular oil changes will it last for a very long time, like most other mercedes? My father has just bought a 99 E240, its the 2.4L not the 2.6 in the newer cars. He wants to keep this car for a long time it has got 66K miles (9K km) on it now. Anything we should look out for?
Thanks in advance!
