I don't know you, so I am basing this comment solely on your post. Your post sounds like a person looking for an excuse. If replacing ball joints keeps you from going to grad school, you either have larger issuers or are a dreamer like so many people I know. Don‘t mean to offend and hoping you are just kidding with your post.
I appreciate your message. I could give folks here a full picture of our situation, but honestly, it would be a VERY long read to adequately explain. I have some severe medical conditions that remain untreated due to no insurance for past 3 years and we make too much for assistance. I spent a lifetime in an artistic field before I married, so all my experience is there. Now 50, married, with a 15 year old stepchild, and unable to just up and travel here and there every 3 months, money and work is very tight. I need to go to grad school as it's a good offer and best option for our next 20 years. My truck won't be paid off till June, and it appears it now needs upper ball joints. We barely can make the payment much less repairs... hence we wanted a bike for me to go to school to allow us to visit on the gas money saved from not driving the F150. However, we dramatically needed something built like iron with minimal cost. The C14 seems the best bet, one under warranty, with ABS, as my two wrecks came on wet pavement and would likely not have happened if I'd had it in the past. However, with the truck, my medical issues, I don't see us having the 7k to get a 2010+ model C14.... and that would be a good deal at that. This is the short answer, and not going into other factors. Sorry, but there's a lot going on here. Thanks.
