It sounds to us like you already have the ideal car in your garage. If you're only using your Peugeot 3008 at weekends and not longer journeys, you're probably not seeing the best from it in terms of fuel consumption. We would suggest trying it for your commuting, and you should find that the fuel consumption is good - our Real MPG figures show that manual versions of the Peugeot 3008 are achieving over 40mpg, which is close to what you're getting from your Hyundai. This would also save you the hassle of selling two cars and buying something else.

However, if you do want to swap for something between the two, you might want to consider the Peugeot 2008. It's a little smaller than the 3008 but still has that SUV feel, and you could go for a version with the same 1.2-litre petrol engine and likely get even better fuel consumption than your 3008.
