No, put the length of time you have actually owned the car, not something made up.
That is an idiotic piece of advice.
Lying to your insurance company is great.....till you have an accident and find out your insurance is void.
I think you all took this the wrong way (Or I didn't explain myself properly)...I wasn't actually saying to buy a quote with this information. But you can't compare insurance on a brand new vehicle to you against one you have owned for 5 years. As the longer you have owned a car the cheaper insurance is.
So I was saying to the OP to get a quote for the cube using the same timeframe of owning the Z....as this would give a fairer comparison.
