Completly agree. That's why my commuter car is a 2000 VW Jetta TDI. I get 1150km on a tank (60L)of diesel. That's with 90%highway driving around 130km/h.
Just as a comparison, the SMART car gets 500km on $22. I get 1150km on $50. By comparing this, the SMART is not more fuel efficient than the VW TDI. With the VW, you get alot more room and luxury. There is way too much hype about the SMART at the moment. Way more than what it really is.
The SMART tops out at 130km/h. I got ~182km/h out of mine 2 weeks ago. Had the Jetta for a year and drove almost
50 000km into it with no real issues. She's around 243000km at the moment. It's fully loaded including leather. Paid $11000 for it last August.
If you wnat to buy a diesel, wait till next January. The ban to add Sulphur in dielsel will be in effect. I bet, alot of the manufacturers will start bringing there diesel models over.
