Hey man, I was messing around (practicing) with Ulead Photo Impact with merging objects. I took a picture of your '89GT and my '92GT and put them together. I'm no graphics artist and this is really the first time I've tried to do this with 2 diff cars, so it's not perfect but looks pretty good. I guess the lighting on my car is off from the lighting on your car, but still looks okay...kinda.
Check it out... i attached it.
