QC Underground Car Park


I have been speaking to Quintain recently about renting a space in the underground car park at QC.
The quoted me £100 plus VAT PCM. I offered them £50PCM. They then came back with £75 + VAT (£90). I then offered £65 but they said £75 + VAT PCM was the lowest they could go.
My question is has anyone else enquired about the car park and if so how much did they quote you and if you got it how much did you end up paying?
