wow, those are really on opposite ends of the spectrum. People who have Honda's seem to love them. I had one for a short time but didn't like it. The GM V8 engines are solid, so I don't think reliability will be a determining factor here. You should really just get what you want. The GTO looks really nice and is a little less common. Are you more comfortable with rear wheel drive or front? I personally like RW drive. Do you have to deal with snow during the winter months? if so a Front wheel drive might be better. (Unless your like me and love the power slides!) Also the SI will get better gas mileage, something to consider for when the price goes back up. It's really going to be about which style of car you like best, American muscel? or Import tuner?
