OEM Windshield is expensive, it's still available, but may take a long time to actually get. It's expensive to ship because of it's size and how fragile it is. Acurapartsforless.com list it as $1800 local pick up only. It's like $2600 retail at the dealer. In the States aftermarket windshield is pretty cheap (Safelite $400?). The rear hatch glass is also hard to find, but I imagine most cars you'll find won't have any damage to the rear glass.
I don't believe the OEM radio is fixable and it's very expensive to replace with a new OEM one ($2700?). Dead radios are pretty common as the cars are all pretty old now. If you want OEM then make sure it works. There are good aftermarket OEM looking options though (Willmans, SOS, etc).
For the body the front fenders, rear quarter panels, and bumpers are still available though shipping times maybe slow. The hood, doors, and maybe trunk are going to be hard to find new and expensive. So keep that in mind if you find a car with some body damage.
