While buying a surf, check the following:
If its Dubai import, check for suspension weakness (remember arabs love off-roading, sand surfing a lot and that takes the toll).
try to buy a Japan imported surf because its a good as new if driven on japanese roads.
See the auto transmission position. P N D R L 2 should adjust as per the set pattern, if not suspect transmission issues.
If its turbo, listen to the typical whisling sound.
Check blow
Check papers (there should be 11 documents, including B/L)
Take it to a lift and check ends for cracks.
Check mileage. If more than 120000, dont worry. If less than 50,000, speedometer has been tampered.
See mileage on the aution sheet (if available).
See 4x4 is working or not by engaging it in H and driving uphill
Check power steering ply. If more than normal, the vehicle needs major steering work.
Check wheel locking system & braking as well.
Mileage 6-7 Kms/liter. maintenance costs 2200 for filter and oil change. 1KZ was converted into smokeless 1KD in 2000.
