I bought a ’74 Challenger, did I get a good deal? Or did I pay too much?

Alright, I just recently bought a '74 Challenger for around $4k. The car itself is pretty straight, there's some surface rust here and there. It had a rebuilt engine, new paint job and new master cylinder a few years before it began sitting. It has a 318 in it from another car.

It also comes with half a two-car garage of spare parts, we're talking six doors, lots of original glass, three spare backseats, five front seats. Lots of stuff.

Another question I have is I'm not certain whether the trunk floor pan is legitimate, there's room to stick my fingers down below on the side? Based on some pictures I've seen it looks like other trunks might have the same crevice but I'm not sure. I should have investigated that more thoroughly in case it's a false bottom and it's completely rusted out underneath there.

Did I make out OK?
