Most of the daunting sounding tasks are actually fairly straight forward, but I find if you research, plan and have the correct tools it can actually be quite satisfying. I have read stuff like " leave it for the next owner", but I am that next owner so I guess I have to at least try. Parts are not that ridiculously priced if you search hard.
I try and think of if as if i try the next task (and it works) and I save the labour costs then that labour cost should cover the cost of my next part... and so on....
I don't really have a long list of things to do - it was just the main 2, EAS fault and Fuel pump which were a pita to deal with as a daily driver.
Also when the suns out it does make you want to roll up your sleeves and get your hands dirty!
