It's got a lot of rust.
I am happy with my Corona 2000. I bought it in 1989 and don't regret it.
It's a good car with a bit of pizazz and some get up and go when you need it. The radio is great, except it only has an AM function and no tapedeck. I'm thinking of having an extra speaker put in so I can have stereo sound.
Interior is nice brown vinyl-easy to clean.
No aircon. makes it a bit hot in Sydney summertime, but turn on the fan and you're right.
I hate to tell you, but installing another speaker will not give you stereo sound unless you replace the radio as AM is not broadcast in stereo, only FM is. But if you just want the sound to go further around the car, installing another speaker will help, but you'll probably end up burning out the radio's amplifier anyway. You can buy AM/FM/CD players for well under $100.
I bought myself a portable trannie instead of getting the other speaker- way too expensive... upwards of $40!
