We are the 6th house on a private road of 6 houses (i.e. the one at the end). Under the terms of our right of way we have to contribute a reasonable proportion of the cost of maintenance.
It’s not heavily trafficed – more a driveway than road – so the residents have sort of left it to wrack and ruin. One resident has decided to get organised and have it resurfaced – quote is about £1250ea at present which we don’t think is unreasonable, albeit we’d probably not bothered having it don’t at present (I think he’s looking to sell up).
Main thing is to ensure you have a right of way and to clarify what parking rights are – just because you can pass and repass that doesn’t necessarily give you a right to park.
<edit> parking is probably the biggest bugbear – the general public tend to just use the entrance to the road as as parking/turning point so you can sometimes find it blocked by a seemingly-abandoned car with no way of passing – that can be annoying!
