Your best basic resource for a question like this is an objective publication that specializes in collecting exactly this sort of information.  For example, Consumer Reports provides exactly this sort of information: be aware, it will cost money if you want full access to their website.  However, there's a good chance that they have the magazine at your local library.

There's also a meta level of knowledge to be gained by people who work on a particular brand of car regularly.  For example, reading what people have to say about modern Subarus was what drove me to buy the cars I have now.  Aside from the AWD, the fact that all Subarus are effectively the same fundamental design layout and engines wrapped in different bodies really appealed to me.  I don't find myself hunting around for a particular component: they all look the same once you pop the hood.

So, if your mechanic friend loves working on a particular type of vehicle, that's generally a good sign.  If they are always cursing about the special code reader that they can only use on a particular model year, perhaps that's an "avoid" signal.

How to find out the "serviceability" of a car?
I have a social marketing admin for my clients. I want to be able to update the admin when there is a new notification on their facebook fan page or a check in at their location.

Currently facebook sends me an email notification (for example when someone posts on the fan page wall). What I need is for a script to run that updates my admin whenever there is a unread notification.

What I don't want is to have to run a cron job every minute that grabs notifications. I have a lot of clients and a lot of fan pages. This would become very taxing.

Is there a way for facebook to push the notification to my script page instantly instead of querying every minute?
