Depends how much you paid for it, what the condition is like, year etc. What would it need for the MOT.
Can you tuck it away in the garage and do it up for use in the spring.
Do you have the time or space to break it for spares.
Bought mine cheap, and bit of work and got myself a cheap rag top to use, and which won't upset me too much if/when it gets too much to keep running.
As mentioned above you must have had some sort of urge to part with the pennies when you bought it.
