More information on this car can be read here;
This car has A LOT of work done to it and it was done right.
IMO, the car is worth close to the asking price taking into account all the work that's been put into it. You'd have to spend at least twice the asking price to get it the same or close to these results.
This has to be one of the cleanest E28's I've ever seen.
BTW...Considering the engine work in this particular car, 250hp is certainly attainable.
You can PM "m-racer" on mye28.com for engine details as I believe he was the previous owner that had the rebuild done.
Keep in mind that there are TWO
outstanding E28 examples in the market right now in and around Toronto and I'd say go for them because they don't come around very often in this condition.
