I've had a '93 nissan sentra- bought at 36k miles, drove it to 225k miles then gave it away to friend when i bought my new car..only problem was replacing the alternator 3x, then at 200k miles, developed a oil leak...1 quart of oil ($1) every 1k miles. so if i went another 200k miles, it would only cost $200 extra. waaaay cheaper than to fix the engine. but since i drove ALOT, it got a little annoying. then got a great deal on a prizm.
bought a 2001 chevy prizm new because dealer cash/incentives/gm card rebate = 1/3 off ($18k invoice, $12k out the door)..currently at 65k miles and running great
A prizm is a corolla with a gm badge. both the corolla and prizm come from the same plant. the only difference is the shell, and interior.
oh, i'm only did oil changes every 6k miles on the sentra and 7.5k miles on the prizm.
so my recommendations are buy a '93 sentra (<$5k) or a 2001 prizm (~$6k).
and the only standby of civics (1996) or Corollas (1996-98). later models cost more than $5k.
2001 prizm is your best bang for the buck since it depreciates fast since not many peiople know it's a corolla.
