Good luck with the move.
I moved 'up the line' from Plymouth about 5 years ago.
We still have sea up here but it smells like seaweed, it's muddy and we have namby pamby tides.
On the good side, not so many potholes and not so many traffic lights either (I used to have to do 23 sets on the commute from Stonehouse to Estover).
Keeping your head clear for sorting the move and paying the deposit on a house has a monetary value. For me, that would outweigh any extra I could get for the car - so I think you did the right thing in the circumstances.
