First up, congrats
Same situation here, desperately hanging on to my Zed, we ended up going for a second car and picking up an 04 Focus Ghia for £2k. Cheap as chips to run really. That said the Zed does look more and more a toy when a baby is enroute but decided I will at least hang on to it till summer so I can enjoy all the modifications I have made - maybe it will move on then - but who knows.
