hello jenarry,
we had the same problem, our pram fitted half in the boot and half on the back seat- and no where to put the shopping. We had a lovely seat ibiza then, now we have a vauxhall astra (new model) and it fits perfectly. But we've also bought stroller for popping to the shops its much lighter so better for the hot summer days anyway, when you pick your first pram you don't really think about having to take it to bits to put in the car, or how heavy it is, or how wide it is, or if the pattern/style will still be fashionable 1 or 2 years later, or if its easy to clean. I loved my first pram when I first bought it 2 years ago and now I HATE it!
oops- sorry a little rant about choosing prams!
Its very sad but you must sacrifice your nippy little corsa and look to buying the dreaded FAMILY CAR- NOOOOOOOOOOOOOOOOO!!!
mondeos, astras, vectras, passats etc
Happy hunting!
mm x
