I just have a few questions about the older style mountain buggy, with the fixed handle. I have been offered a second hand one and do like the look of it, but haven't actually seen it in the flesh yet. I went to our local buggy shop yesterday to have a look at the newer style one, and it seems very wide. Is this the case with the older one? I can't seem to find a website that does a comparison. Are there any other major differences?
