A friend has a 1975 or 1976 (I forget which) Datsun 280Z that that he
would like to have professionally restored. Can anyone recommend with
confidence anyone within, say, 50 miles of NYC, preferrably in New York
or Connecticut, who can handle such a restoration?

I'm working on an 84 turbo 300zx.
There is a single wire that connects on the driver's side of the intake
manifold.  When I was working on the motor the wire broke off and I
need to replace it.

I have a 1990 Nissan 300zx and I love driving it until it gets cold
outside. When I try to turn my heat on it blows luke warm air but it
isn't hot enough to defrost my windows or keep the car warm. I turn it
up all the way to 90 but I get the same old luke warm air. My A/C
