It really comes down to what type of car you are looking for etc. I personally love my EP3, but prob. for different reasons than say a 350z.

As far as insurance goes, beyond the normal stuff (age, credit, driving record etc.) the car itself can play a factor. i.e. A porche can be more expensive to insure than say a Honda Accord, ilreguardless of the orginal MSRP. A test would be to call your insurance company and ask how much it would cost to insure an old 90's Z.. I bet its not all that different from the 350..

Also SHOP AROUND, there really is massive differences in costs between insurance company's. EX: State Farm and GEICO look at driving record.. while Progressive and AllState look at Credit.. For me it was actually cheaper to go with Progressive, because my credit is so good than State Farm, because they don't care about my credit.. just my age.
