I want a mustang soo bad, I like all models.. but I am thinking about the 94-95 5.0 because the insurance rates will obviously be cheaper than a 1999+.. I was wondering do the 94-95 5.0's eat up ALOT more gas than the newer 4.6 liters? or is it not that much different?
as for gas milage, it will likely depend upon the mods, tune, etc. a car with clapped out sensors might not do so hot (for either a pushrod or mod motor).
what motor do you prefer? if you have the coin for a newer model, with a 5.0SN you would have mod money.
go drive each and see what you like. might also read each's sub forum to see what people like/gripe about.
