I am glad to see more positive posts.
My project was pricier than yours to start with
If you have a spare ride and decent toolbox,don't listen to anybody with crappy attitudes,it's your money and your time you are spending,it's nobody else's business.
Enjoy it and if not,part it out,you'll make way more than $2000.
