Okay, I just had to get my wife's car serviced, and the mechanic tells me some things that are plausible, but I'm not quite sure about. People here tend to be knowledgeable about anything, so I'll ask any auto nuts present.
Is it true that Saturn Ions('04, to be precise) use very specialized batteries, and for some reason, mount them in the trunk? The problem appears to be a bad battery, but due to the odd location, special casing, and odd battery, it's running a lot pricier than simply buying a normal battery and swapping it. Is this true, or was the mechanic bullshitting me?
