Well context is everything, I’ve had a brand new transit for £28/day but it was over easter and the office was shut for 3 of the days so they had a special on for longer hire.
£23 from a big supplier in a very quiet time might be possible.
If you have been through the comparison sites above and tried a few of them for a direct then that is probably the best price for your times and requirements. Try looking at bigger cars though as sometimes the tiny ones are more popular.
Failing that is the price in your budget? If so book it.
