    This is a fine looking car from the outside. The interior is a little tatty, understandable for a 30+ year old car. The install looks like it could be factory from the limited pictures.
    I hope the conversion isn’t recent as GM has a 3.6 turbo with about 410 HP and almost 400 pound-feet,
    and a newer version 3.0 twin turbo with about the same numbers which are almost twice what they installed. The person that did this swap must have been a real G.N. enthusiast. Nice car, good looking build-out.
