Price?

What is a 1975 911 Targa with a rebuilt 3.0 Liter engin worth. The car has recently had an off frame restoration job and is in very good condition. It also has A/C.

Thanks for your help.

I paid for mine this year which is a 1978 911sc targa with a rebuilt 3 litre engine and full body restoration I paid £8750 ponds sterling.
Hope this gives you some kind of idea. It might be different for the US
