Hi all, i'm a poor college student and i need to find a RELIABLE car for as cheap as possible. will probably be getting a used car from a private party on craigslist or something. probably a 1994-1997 toyota tercel, corolla, camry, honda civic or nissan sentra. i will be getting a clear titled car

factors to consider:
cost of car
cost of parts
cost of maintenance
mpg (though they're all pretty similar)
i need an automatic

right now the costs of the cars are in this order: lowest to highest
tercel
sentra
corolla
civic
camry

i plan to drive this car around 4-5 years, and i want to not have to bother with maintenance so much and if i do, which car has the cheapest? i heard civics have the cheapest parts, but a civic is about $1000 more than a tercel.
but i don't know how much maintenance i'll have to put into the tercel and if i do, would the prices add up??

thanks for your expertise. share any stories/experiences about the mentioned cars or any warnings.
ALSO

i plan on getting a car with around 100-150k mileage
so i need one that will last me 4 years, i don't really plan to resell it, but it's a possibility. even if just for a couple hundreds...
i won't use more than 10k miles a year and they're mostly going to be freeway miles
ALSO apart from craigslist, ebay and yahoo auto

where can i get used cars for LA area ? cheap and reliable?
thanks
preferably private parties. sites
does anyone know how much it'd cost to fix the AC and horn for a civic?
thanks
