hi ive had a sportrak for 5 yrs its been a good wee machine, im looking to buy a decent fourtrack now, i know that they had more features as they got younger like a.b.s. ,alloys, and im curious about the flick switch from 2 wheel to 4 wheel while on the move, and is a full service history very important with this vehicle, and what to watch out for on non f.s.h. models, any info would be really helpful, cheers
