Help / Opinon on Value - 1971 SS 396 Camaro

[b4cmaro]

Guys - I'm out of my element with a second Gen car - have been wanting one, but, havent gotten fully educated yet. And dont you know, I found one that I might be interested in.
1971 SS 396 - blue on blue, 4 speed with A/C. The original radio is gone and the 10 bolt was swapped for a 1970 model 12 bolt and someone put a 402 sticker on the breather.
Odometer reads just under 17,000. Receipts for an engine rebuild at around 13,000 miles in 1997. Supposed to be a numbers matching car.
Car was built in CA - I was counting on it being a Norwood car so the trim tag would tell me everything. It does show the right color for paint and interior. Any designation that would show the LS3 and 4 speed on a CA car?
I have seen some pics and it looks nice, very nice. Just not sure about prices on these cars. Ideas and opinions?

thanks
