1968 Dart 270 Hardtop, buying questions!! (VIDEO ADDED)

Hi everyone!
Not sure if this is the right subforum, but I didn't see a particular section just my question.
A co-worker says he will sell me his 1968 Dart 270 Hardtop, says he is the second owner as him and his dad bought it from the original owner about 7 years ago.

It has the original 318 V8 2bbl motor and 3speed auto trans for $2000. Mileage is unknown, estimated at about 150k, odometer stopped working at 12,014. Power steering, NO power brakes, 4 wheel drum. AC compressor has been removed, as it froze up.
It runs good, car drives OK, has some squeaks and creaks in the suspension, like it needs new springs, but he did just put 4 new shocks and tires on it.
Minimal rust, just a little on the back bumper on top, making the chrome peel bacl, and some bubbling on the drivers side quarter panel, owner says from a bad bondo job when he had it painted.
Trunk floor pan is in great shape, floor pans too in the pasg area, the underneath of the car looks good from what I can see, without taking it to a shop to put on a lift.
It has hooker headers and dual exhaust, it sounds great too.
The inside needs some work, missing pieces, turn signal cam is broken, flashers don't work, he has the original radio for it too.

It's a california car, I have decoded the vin and fender tag too.
I looked up the value of this car, and in poor condition, haggerty says it should be worth about $3500.

What should I look for in particular? And special things on these cars I need to know about?
He has allot of extra parts with it, badges, a new rebuilt 4bbl car and a intake manifold, etc.
