It is pleasure to be a owner to this sedan, what may be the roads. The hills, mountains , plains even the desert rough terrain. This beast glides everything like a butter. I still get an average of 20+ kms / ltr. (highways)
To suggest is to add an electric fuel pump to eliminate any kind of fumes that one gets during the summer. It will be like a pacemaker for the engine. I own this vehicle which is a 1992 make, still on the highways it cruises at a speed 130km/h. Amazing.
The only on line I know for this vehicle is keep going.
