This is a car for someone who wants to collect, not to use. When it runs, it is incredible fun. The major issue is the availability of parts specific to this SVO Turbo model. Major parts like timing belts and core engine components are no problem, but things like wiring harnesses, and exterior trim parts are impossible to find outside collector clubs. I started having electrical problems with harnesses that were going to have to be hand made and wired, which was going to cost at least a thousand dollars to do. I sold it to a mechanic who could never identify all of the misterious electrical grounding issues it had after rewiring. For the most part, mechanics will not even take on these cars because of the wiring problems they had.
A great car when it runs, but don't count on it as dependable transportation. If you find one, have it professionally restored, and then store it until it becomes a collector's item. Definitely a head turner though. I would always find crowds around it in parking lots! Very fast, and incredible pickup when the turbo kicks in.
I also own an 86 SVO. They're great cars to drive when they're running right, however lack of aftermarket support makes it difficult to keep them running well.
Most Ford dealers don't have a clue how to work on these cars.
Compared to a 5.0 GT, the SVO has slightly slower standing-start acceleration, but the SVO handling is incredible. You'll be out looking for twisty roads.
