in december i will be looking for a new (used)car. it will be daily driven but i would also like something that i can occasionally track. i have never raced before and i dont plan on going crazy with events or mods. upgraded brake pads, tires, stiffer springs. I have about 8k to spend on the car. so far i have thought of a few cars that i thought might fit the role, but tell me what you guys think.

-Acura RSX
-Ford Focus SVT
-03ish Nissan Sentra SE-R

i may be completely off base with the cars, but they fit what i am looking for, good on gas, cheap, reliable, easy to work on, comfortable and decent handling. it also has to have a back seat. so i am open to suggestions.
i am not looking to win necissarily or have 300+ hp.

sorry for any typos, im on my phone.
