Missing the most important consideration, regardless of how good or not the 3008 is.
Come resale / trade time the depreciation on the 3008 would be massive compared to the Tiguan. You'd retain an easy 55-60% on the Tiguan after 3 years and about 40% on the 3008.
Our lease provider actively discourages the purchase of any Peugeot (and a number of other less popular brands) for this reason. They even consider a Skoda (as good as it is) as a risk for the same reason.
The $5K you spent extra for a Tiguan would nothing compared to $$1000's you would get less for the 3008 at the end.
