Family growth – drive Lim or buy a station wagon?

Tomorrow together, I need a small decision aid. I am the father of a daughter and had to find out that a golf lim is too small if you want to go on holiday. Child 2 is planned for the end of next year. Conditions: Vehicle up to date: Golf 6 and very well maintained with 160 tkm on the clock EZ 10/2009, power: 25 tkm/year To estimate the current VK: (except for repair of the auxiliary heating were no extraordinary damage to repair) – accident-free – large Navi RN S510 – Ex-works floor heating – sliding roof – alarm system – manual transmission – sports seats – no Xenon Runs quietly and has never ticked. After DAT I get 5200€. Therefore my thoughts: 1. Use roof box 2. Sell car now as long as I still getetas 3. save and if you need to buy new car – reserves should not be touched. – Saving volume in the year 6500 € + X Price new vehicle: Skoda Octavia – Golf 7 or 320d always as a combo (19-2 3 t€) Heating and xenon are a MUST, automatic nice to have. I would do without the SH at the BMW. How would you decide? Greeting from BS
