If you cant get motivated you could try the following couple of things:
Firstly, you have a list and that's a great way to get started. Now you just need top pick a ride to complete. Only work on one project at a time, if your waiting on parts for months then box it and move onto the next project.
When it comes to what car to work on here is what i do. With the list write a number next to each build, a number between 1 and 10 for how much sentimental value the car has.
1 = Why did I buy this piece of junk?
10 = its my first ever RC car and you will never prise it from my hands![/list]
Now a second number between 1 and 10 for how close you are to finishing the project.
1 = I have 1 wheel from a works 93
10 = car is done, all I need to do is get the body painted
Now, add the 2 numbers together and the car with the
highest total is my what I will focus on to get finished. All of my efforts will go into getting this done and shelved, running, or whatever.
To get the juices flowin I will then look at liveries or something, i.e on Pinterest/google

Or search google images for the car i'm trying to complete, i.e for a kingcab or hi lux

Second thing, maybe you just need to give it a rest for a while. I know how easy it is to get up with the hobby. I noticed I wasn't giving my girl much time, and she didn't say much as she knows how much I enjoy it and it allows me to unwind! So when I saw the error of my ways I decided to devote more of time with her and other hobbies and give the RC stuff a rest for a while, we did loads of stuff: went to a judo classes, picnics in the park, bike rides, even did a bit of travelling. The RC stuff was still there when I got back!
I hope this helps! It is a funny old hobby!
