Those prices seem OK. I bought a 200SX GT new in 2001 and I was in my 30's with a good record, car garaged etc and the best I could do was $1900. Most companies wouldn't insure it at all or quote stupid prices like $4000 or $5000.
Subsequently, it was stolen from the dealer's workshop, Ryde Nissan, when it was getting it's 1000km "wash". I never received an apology from them.
They gave me a courtesy car for 2 days then called me up asking for it back. I told them they could have it back when they gave my car back. Farkers!
