A friend of mine found a 1984 2.3T GT T-top car for sale. And I have never heard of this combination plus the fact that it wasn't a SVO. He can get the car pretty cheap but he wasn't sure if it was worth it to buy it since it has some sort of a mechanical problem that the owner can't figure out. It this a real low production car, the owner said something about 1,800 being made any info would be appreciated.
The t-tops I think make's it even more rare. This link shows a production of 3,386 that year but does not break it into t-tops unless they all came that way. http://www.mustanggt.org/gtnumber.htm#other As far a mechanical problem that is all the more reason to grab it up..
check on GT350R's site, all the info you could want. Its a rare one for sure. http://gt350r.stangnet.com/ Dr.
350 hatchback 2.3l turbo's made in 84. they should be white with canyon red interior with svo seats. not sure how many rear t-tops. i'd buy if it were cheap and had no rust.
