break it? Basically on my ST200 , the coil pack and Maf sensor need replacing and to top it off the power steering pump has now died

.
I`m a bit reluctant to spend more money on it as its done a few miles, and i`m wondering if it will be worth it because it owes me less than £1300.
Do i cut my losses or find the cash and hope nothing else goes wrong?
Just looking for other peoples opinions...
Thanks, Ed
