It's a nice T/A, Whats he asking for it? Make sure you decode the VIN# to see what it really is. Just because it's a CA. car don't assume it's clean, check for any rust under the car, I'm sure he won't let you pull up the carpet but you'll get an ideal of how the floor pans are by crawling on the ground for a few minutes. Same with the trunk. If it's in the Bay area that mean's salt air, check the seams and any of the bolt areas where salt spray could settle, Why do I know these things? Been there done that
My 2nd 78 T/A came from the Florida coast and the body looked GREAT, after buying it and digging into it a little I found problems like I described. Thats why I'm on my 3rd T/A
Here are some pictures of my 2nd T/A when I bought it....looked great but looks can be deceiving. I'm not trying to rain on your campfire...I just you to be happy with it after you buy it.
