Hyundai Elantra is the best car, when it comes to after sales services and low maintenance, but yes Renault Fluence is also a low maintenance car, and you don't need to take it to a service center than often.
Volkswagen Jetta is a good product, it comes with two engine options; 1.4-litr TSI petrol and 2.0-litre TDI diesel. Both the engines perform well, the 2.0-litre diesel engine comes with two transmissions, 6-speed manual and automatic transmission, while the petrol version comes only with manual transmission. The diesel engine performs well in all conditions. Volkswagen Jetta 1.4Litre, 4 cylinder TSI enginecoupled with 6-speed manual transmission gearbox is high powered, extremely frugal. This amalgamation is good to generate a very healthy 122bhp @ 5000rpm and a generous 200Nm of torque @1500-4000rpm, however a bigger petrol engine would be welcomed.
