Oil change, coolant change, trans pan drop and shift kit, plugs, O2 sensors, belts, wires, filters... Then suspension, brakes... Then when all is good, MOD!

Pick your poison for your $100, but it's not going to go far and is an unrealistic approach to a 125k car with unknown history. What does the oil look like, trans fluid? How about plugs? Have you even taken a look?

Want to go fast and have ****ty or no brakes? Sounds great, good stuff! Go for it...
