I bought a 1998 Elantra in December 2002, with 28,000 KM. (1.8L engine with a manual transmission) Mileage now is 77906 KM My driving is 99 percent highway. I drive 300 KM per day. I'm a conservative driver 105-110kph on the highway. I have driven 49,002 KM from December 11/02 - August 28/03 From January - March (temps -30 to -10 Celsius) = 7.283 L/100KM From June - August (temps 10 to 30 Celsius) 6.527 L/100KM BTW I found a good personal site for conversions, [URL]http://www.euronet.nl/users/grantm/frans/fuel.html[/URL] In my opinion, there is a small gain during the warmer months. I have installed a K&K filter. I like the filter, but don't know if that has made a difference. The only cost so far has been to replace the right front wheel bearing. Cost $220.00 cad. Other than that, only schedule maintenance. I added a cruise control after I bought the car, and have to take it in for warranty work. Overall impression....It is a solid little car. I am 6 ft tall, and my only major beef is I wish the tilt steering would go up another inch. The sun visor doesn't help much either as it blocks my view of road when down (I sit too high) Air conditioning is more than adequate. The volume on the radio does not work right away in the cold months. Car has to warm up inside for it to work. No big deal. The brakes have been making noise that last two months though. They stop for a day or two after I wash the car, but it starts up again right away. They squeak when you go low speeds, even when you don't press the brakes. A TSB states it happens during the warmer months. I will wait and see this winter if this is true. We'll keep you informed next year on the cost of the car. So far so good.
