Family growth!What’s going on?

So hello for the first timeBecause I and my girlfriend are expecting our first child, I am now looking forward to looking for a suitable car for a young family.I look forward to this event with a laughing and a crying eye because my beloved and hard-earned CLK 55 must be gone.(Try to convince my girlfriend to keep the CLK as a second car failed).So now more precisely it should be a spacious soda so ala 7ner.Bin already the 745d Prob It’s a diesel.STAUNLICH.But the 7er didn’t really convince me either.Most of all, I prefer an S-65 AMG but unfortunately it’s too expensive which alternatives could you recommend to me?
