Silver Wheels Insurance

Well thinking of insurance for the Dart.My regular insurer witch was alawys cheep and never ask for an appraisel now wants one done.I know were thatsss going oooo 25 grand we want 150 a mounth.Quick call to silver wheels at 25 grand its like 300 for the year.So who here is useing them and how are they to deal with.The last time i had an appraisel on a 69 camaro 20 years ago at 10 grand they wanted 1200 for the year.So all thoughts on Silver wheels please.Good and bad.
