This is my first thread as I am a new member and just purchased an 2007 V6 Mustang. It has 95K miles on it, normal wear but still runs/drives fine. I had it looked at before buying and was told I will need to replace the engine thermostat housing soon because it should be done for any '05-'09 Mustang reaching 100K miles (its not leaking yet). Also just normal maintenance (serpentine belt, fluids, rear gear oil, etc.) to be done. Other than that i was told it is in great shape for the mileage. I purchased this car because it kinda fell into my lap and as i just recently left my previous employer who was supplying me with a company truck to drive, I needed a reliable car and quick. So now I'm curious if i can add some upgrades without risking engine life or if it is even worth it on a car nearly 10 years old with 95K miles. My question is their any risks to modding a vehicle of this age/mileage? I wont be looking to boost crazy HP, just looking to add rear end gears (3.73), CAI, throttle body, have it tuned and add an exhaust. Other than that maybe struts and coils? Any input would be appreciated!
