Don't know what your budget is I've not had a Terios but have had disco, mitsubishie pinin and a Jimmy. All were capable disco was heavy and cut up the ground , pinin was expensive to run and service and the Jimmy was tight for space inside but excellent off road. On road the Jimmy isn't the best and yes they do suffer from the tin worm. I've currently got a dacia duster 4x4 , and can't fault it. It's the old Nissan x-trail system and is just as good off road as Jimmy but much better on road. If you can stretch the budget a little might be worth considering. But if your getting a decent deal on the Terios put decent tyres on it and it will do what you need as long as your sensible and they do look good fun. Not sure but think they have a viscous coupling for the four wheel drive system instead of the landrover / Jimmy system of clunking leavers to the gearbox
