One thing that has not been mentioned, and I really did not ask specifically is parking.
Can one pretty much park on any street that is not marked or posted as no parking?
I've noticed on some streets there are people that put stickers on windows and collect a fee. Are these official? Are the fees set or arbitrary?
Are parking lots a good choice? Are they safe?
I've read that car thefts are very common in Lima. Should I be worried about parking on the street? (There will be some neighborhoods that will be obvious to avoid, and I'm not likely to be driving in them, anyway.)
I will buy a new car with a factory alarm, but I'm not sure they are really effective. Would something like a Club steering wheel lock be good to get?
Nobody, will do anything if your caralarms sounds. Nobody is going to risk their life for your car.
And those steering wheel locks can be removed in minutes. (A professional removes it in a few seconds).
Don't interfere if you see someone stealing or breaking in to your car. You will likely get stabbed with a screwdriver.
Drugaddicts (fumones) will approach you when you park your car and offer to look after your car if you give them a tip. Best things is to pay them. Off course, they won't look after your car but if you don't pay them you might find your car scratched when you come back or parts might be removed or in the worst case, your car might be gone.
There are guarded parking lots but they aren't 100% safe either.
Keep doors locked and windows closed when driving and put valuables out of sight. It's common to smash a carwindow at traffic lights to grab a handbag.
