This scenario is pretty much what a large car supermarket is doing at the moment. You buy the car, they deliver to to you for free, and provided you don't do more than I think 50 miles they will take it back for free within 7 days if you don't want it.

There is a clause in there that they reserve the right to sell it to you in the first place if they believe you never intend to keep it, so presumably that means realistically you could try one car and swap for another, but they'd probably not send a third one if you returned the second car they sent.

In terms of the legality of driving it, provided the "test drive" is a journey you'd be allowed to make anyway (e.g. to the supermarket, work etc.) that would be fine. Realistically, if you don't need to do one of those within 7 days, there's not much point wasting money buying a new car at the moment.

If the court finds in your favour in this scenario, would a paid Fixed Penalty be refunded ?

It doesn't work like that - if you accept the FPN you pay, if you don't accept it or want your day in court, you don't pay until the court decision.
