Hello Teresa,
Welcome to the Club and the Forum.
Wow, That's a few questions you have here.
Are you testing us all; trying to keep us all on out toes ?
I have never owned a Fiat Panda; you will experience a huge difference, I am sure.
An Alphard will easily accommodate two bicycles, some members transport their motor cycles.
Buy a rubber mat for the bikes. I us one to prevent unnecassary mess from my beloved pooch
Actually, the fuel consumption is quite good; but not, no doubt, when compared to a Panda.
The engines (especially the V6s) are very torquey, so you don't need your right foot much.
There is at least one thread regarding actual real life fuel consumption on this Forum.
I don't think any of us have the faintest idea what will happen with fuels, emissions, ULEZ etc over the next decade or more
If I had to guarantee anything, it will be that taxes will increase whatever you drive; electric / hybrid included.
I humbly suggest you decide on the now, rather than what the future may, or may not, be.
All the Alphies Vellfires are about the same size, and, compared to a Panda, are pretty big !
V and G are different distribution channels resulting in a few small trim differences.
As with all vehicles, consider the important options, ignore the rest, buy the best you can reasonably afford and, imho get an RAC or AA report before committing to purchase.
The main decision might be ready converted, or not ?
I feel sure you will receive many other helpful suggestions.
