In 5 years $5,000 will seem cheap. Enter with your eyes open and know it'll be a project that will take time and money. Most (if not all) parts can be sourced.
Do you have a committed space to complete the car ? Projects always takes longer than expected....and sometimes they sit for extended periods.
On the East coast basket cases start at around $2,000...we'd kill for a rust free project !
Good luck...sometimes you just have to go for it.
