I'm looking to buy a new car and while I was looking at 05-09 GTs I found out about the Mach 1s. I found one in a 100 mile radius, 115k miles $8k price tag (new car price range $8-11k) which I couldn't imagine a deal any better except maybe if the miles weren't as high. The only thing is there is no picture of it on the Internet, so I'm definitely going to have to go see it before I actually consider it over the next gen GT but if it's in good shape, mostly stock then I'm probably buying. After I buy it I'm changing out all the fluids with Royal Purple (coolant/transmission/motor oil), replacing the spark plugs, replacing the radiator hoses, replacing the fuel filter, replacing the battery and maybe the alternator, and running a fuel system and induction cleaner through it. What I need to know is before I change out the fluids, how do I know if I need to take the car to get something like the coolant actually FLUSHED, rather than just draining it at home and putting the new new in? And also, any other inexpensive replacements like the spark plugs, hoses and battery that you know of that'll keep the engine running as good as possible? 115k miles and things gotta last a while longer, gonna nurture it like a baby if I get it
