> In NYC with clean 15+ year driving record my premium is $270 a month

This is terrible. In Germany (major city) I pay 166 Eur a month for two cars, one normal (premium brand) family car and second being V8 coupe. I make about 25000km a year in total and have 6 years no claims. No accidents in my driving history (over 15 years). Price is for full coverage with low excess.
