I think if you choose to buy the current model you should look to get a useful discount - 15 to 18%. I was surprised how much I got off list price last summer and this should go a long way towards offsetting the difference in the used value of an ix45 vs a SF in 4 years time as you won't get any meaningful discount on a new model. Personally, I don't really like the look of the ix45, too current, too trendy, too many creases, angles and panel shaping. I prefer the more traditional upright utilitarian stance of the SF and I guess it results in more room. If the ix45 turns out to be far superior mechanically in terms of engine performance, suspension, 4wd and gearboxes then that would make the decision more difficult but I don't think that level of change is on the cards.
