Thinking of the one to select from this cars, will like you to take price, fuel consumption, maintenance affordability(most especially spare parts), durability and reliability into consideration. The cars in question are;
1. Mercedes Benz E320, 2002 model, V6 SOHC Petrol engine with automatic transmission.
2. Mercedes Benz C180-C220, 98-2002 model, I4 DOHC Petrol engine with manual transmission.
3. Audi A4, 99-2001 model, manual transmission, Hi DOHC petrol engine.
@Sienna, will appreciate if I can get a comprehensive response from you cos it's like I read it on one thread here that you use Audi A4. Thanks, waiting for the responses of car experts...

Patiently waiting for people's response...

I ll go for Mercedes Benz E320, 2002 model, V6
Just love any benz product because of its durability and its also made for luxury.
My family, including myself is a benz family.

Go for C180- C220, it is the best and most economical amongst those listed cars.

Redstone: Go for C180- C220, it is the best and most economical amongst those listed cars.

You will not believe it that E320 is more economical than C180-220 series, this is what I just got on fueleconomy.com. E320 uses less than 10litres to cover 100km on the highway while the C-class uses about 11.2 to cover same distance.

Please anybody using this E320 2002model Mercedes Benz should please share his experience.
