That car is virtually the the same history/background as my car, although mileage is about 10k more on that car. If the shell was rust free to start with pre restoration, then it wants snapping up regardless of the price (obviously without seller taking the piss too much) you could easily end up spending thousands putting the body back to how it should be, cars like this don't hang around for long, if in any doubt, get an independent engineers report for piece of mind, the crucial thing with this car would be previous rot, and accident damage... for me, it should have none at the price.
worth paying a little over the top? absolutely!
