FYI,
Ryan Yu reviewed the old Suzuki Grand Vitara. The current model which Suzuki has in their showrooms is the new one equipped with the same engine as the Toyota Rav4.
This makes the Suzuki a good choice against the RAV4 or the CRV. CRV runs apx 6.8/L to 7.4/L from experience. Expect the Suzuki and RAV4 at 7/L
