Advice on price

Hi All

We have a few decisions to make in the household. Keeping it brief one of our boys has disabilities and we bought the roomie for my wife as its easy to get him in and out of the back seat.

We are eligible for the motability scheme that will allow us to pick something bigger like the new ford tourneo connect and maybe look at wheelchair access.

So thinking ahead and bearing in mind he is 6 years old and obviously getting bigger it might be the better option

Sooooo we have a '64 plate Roomster Black edition with about 600 miles on the clock with all the Black edition spec plus OEM bluetooth. Its unmarked

If we decided to go for the bigger option, how much do you think we are likely to be able to sell it for privately and are these Black editions in demand (look amazing to me)?

We bought outright so theres no finance complications and I am aware we will lose money but hopefully not too much
