Question on rear seat room in a w124

[92-2.6]

I currently have a 190e that has been a great car. We now have five with one kid in a baby seat and the 190e is just too cramped to accommodate the family on anything more than a short trip.

I've tried searching, but really haven't found any good info on how much more room there is in the w124 chassis cars than my little 190e.

Personally I'd love to have a 560sel, but I don't think I could deal with the cost of keeping it filled up these days.

Anyone out there have some real world experience using a 300e as a daily driver family car?

Thanks,
Dean
