We got our first car recently and were chatting about it with a couple of friends who've just had their first baby. The car's nothing unusual - a normal sized hatchback - but DH was saying how he was pleased with how it drives and we're planning to keep it for a while.
One of our friends replied: "Fair enough, unless you find that your space requirements change in the coming years" and they both smiled.
As it happens we have been TTC for a while and would still envisage keeping the same car if it did work out. Am I being a bit naïve to think beyond a certain point it's really just a matter of personal preference? Reviews for our car said a normal sized pram would fit fine and we've had no problems with bulky holiday luggage. If we had a massive estate car or 4x4 I think we'd be tempted to fill it with junk or "just in case" bits you never use.
