The time to sell up is when you start a thread called one of the following:

"thinking of selling the cos"

"thinking of breaking the cos"

"stupid cos, so expensive, going to sell"

"this is not a for sale post"

"please talk me out of selling the cos"



Your cos has to be one of the nicest out there for all round looks and performance but circumstances change and sometimes you have to move on to other things. Maybe wait until uni is finished especially as you only run it for part of the year, not like you have year round daily drive expense.
