X3 in flight Unless you can do all the labor alone, hiring a shop will only deplete your finances and leave your vehicle half assembled. It seems regrettable to dismiss a "almost perfect" and rather unusual vehicle; yet, unless it has emotional significance, your optimal course of action is to transfer it as a project to someone aspirant in its current condition. Otherwise, it will just induce financial strain and familial friction, ultimately resulting in an inability to recoup repair expenses.
I worked in a restoration shop for several years. The sentimental projects were frustrating; I attempted to inform the customers that they were wasting their money, yet they insisted on reviving those irreparably damaged items, believing their descendants would value them. In reality, the same investment, if allocated wisely, would have yielded far superior results.
