gr8ful,
Well, it certainly sounds at first blush like the car needs a total restoration. Do you know what is entailed from the standpoints of complexity and cost? I would shop for a restorer not based on location, but rather on reputation. Saving a few miles is nothing compared to living with a poor job.
If you would like to contact me off forum, through the email or private message functions, or through my website, I would be happy to fill you in. I've done a lot with these cars over the years, and the MGA in particular is my favorite. I would like to see you get off on the right foot.
