Thinking about purchasing a 79 SWB whats it worth?

[Rangerman]

I know this is hard to answer with no pics., but trying to get a general price range.

Found a 79 Chevy SWB, its the Big 10. Ive know this lady for almost 10 years and everytime im at her house I ask her when is she gonna sale me that old Chevy. Well she came out and asked if I wanted to buy it, lol.

Lady has owned it since 1984. She has done alot to it over the last 30 years, shocks, brakes, cleaned the gas tank, converted the AC to the newer freon, new carb., had a 400 taken out of a old caprice and rebuilt and installed in this truck....I could go on and on about all the little things that have been done as needed in all the years past.

The trucks interior is stock and almost perfect, this truck has sat in her garage and was driven occasionally and started once a month or so. The dash is not even cracked.

The exterior is decent, has a few small dents and scratches and the clear coat is flaking everywhere. Has rust around wheel wells and rockers, not bad but its there.

Lots of little things wrong as expected, windshield cracked, windows wont stay up, and thats all I noticed the few minutes I was there. Im sure theres plenty of other stuff wrong.

I was considering this for my son who will be 16 shortly.

Do you guys have a rough price for this truck?

Is the 79 a desireable year?

Any major things to look for when I go back to drive the truck saturday?

Thanks for all the help.
