Nope no flames, I was just trying to figure your math.
Admittedly the older gens of both cars cannot compare to the tech now, but I have owned a 97, 03, and a 08 and I still have a 65. I will say the 97 did have a few noises here and there, but the Cobra was pretty solid. And yes I know you were referencing the Maro's as well. I had a friends Iroc Z for a stint...yeah that thing had all kind of sounds coming from it.
It would seem that the new Maro's will take to F/I very well. Maybe to well. It will be interesting to see what they can take before the tale tale sound and smoke comes from underneath the hood. You know someone has to try..every performance car out there will have someone who will push the envelope. Its all in the fun !
I am not some diehard ZOMG do not say anything about a Mustang, I know their faults and strengths. I just bring up facts and point out the small things when I see them in threads.
I like cars. From imports to domestics, I like cars. I just happened to like Mustangs the most
For the OP, it really seems he has bigger problems. Somehow I do not think his Maro should be slower than his GTO. If anything it should at least be on pace with his GTO, not fall behind it. break in or No break in. Nope, sounds like this one needs to see the dealer again.
