I have a question about the 1991 Shadow.I'm finding tons of good info here, I thought it'd be the best place to ask.

I've been looking for a solid Shadow for a couple of months now, and ES with the 3.0 V6 or 2.5 I4 turbo. I've located a 1991 Shadow ES Convertible with the 2.5 turbo, but I'm not sure if the engine is original to the car. The reason I'm suspicious is because the hood of the car is flat, when I was almost positive that the cars with the turbos and V6s had the 'hump' on the left side of their hood.
Am I wrong? I'm just weary of a swapped engine, because you never know if it has been done properly unless you've done it yourself, and I'd rather not have to deal with any issues arising from someone's bad handiwork (plus, to be honest, I'd rather start off with everything on the car completely stock).
All answers are appreciated, thanks in advance
