Check the sunroof drains are not blocked and/or detached where they join in the footwells which could be the cause of the damp and mould. Check the carpets for dampness, they can hold an awful lot of water that can take a long time to dry out even if removed to air. The rear lights are also known to leak into the boot so once the dealership gets the boot open check the spare wheel well for water as this can flood into the car as well.
Parking sensors aren't generally a big deal and if you do purchase i would suggest the 160 map as it will transform the way the car drives.
Sure there will be more knowledgable people along soon with other things to look at.
