I've been with State Farm for over 25 years, the last seven with a sports car as my only vehicle. I asked today about a 2013 Viper being my only vehicle and they said sure, for $2,100 a year, which is about double the premium for my 2011 Corvette base coupe. Well now I know what's the worst that can happen.
It could be they're still basing it on the sticker price because when I asked about a Corvette 427 early in its production run they told me something like $2,000 a year but now it's down to only a tad above my base coupe.
