Buy Honda CRV used from BJ 2008 as Touran Replacement

Hello dear forum community, we love to buy a CRV. Our Touran is for sale and is to be replaced by an SUV with as large a trunk as possible and still not exuberant maintenance costs. Well, the trunk is not a comparison to the Touran, but it is still possible. It should be an automatic with about 60,000 km and from year of construction 2008. If possible in the executive equipment. Currently I have the following offer: Honda CR-V 2.0i-VTEC Automatik Executive 1.Hand, EZ 01/2008, 69,000 km seat heating, leather, glass roof, xenon headlights, fog lights, park pilot, darkened windows behind, summer and winter tires, check booklet for 17.400 €. Should we now decide for the CRV, what does it look like with roof boxes. We have a basic carrier (no original) and a box at the Touran. Can this combination be easily mounted on the CRV, or is original accessories necessary here? Which children’s diseases should I pay particular attention to? Which equipment should I provide? gsvariant is necessary to connect the mobile phone to the audio system? Actually I wanted to look for a CRV with Navi and return camera, but the Navi should not be the hit anyway or?
