I have a '98 trans-am and a 2007 honda civic, and the civic costs about $160/year more to insure than the trans-am. Both have identical coverage including full collision/comprehensive with a fairly low deductable, and increased liability coverage because our combined income makes us a fat lawsuit target.
Hell, if I ever get really sued, it'd be cheaper to just shoot the bastard and his lawyer. That way my wife would get to keep the house.
