I'm almost positive the '02 325i would be cheaper to insure than an '05 RSX Type S. The only fair way to distinguish two cars is by their ISO symbol, which nearly all major insurance companies use. ISO is an outside vendor that determines a vehicles symbol, 1-27, with 27 being high. Acuras and BMWs typically have high ISO symbols, but Acura's are really high, presumably due to their high theft rate.
I'll look up the symbols tomorrow at work and post them up - check back for symbols.
My question is this - why are they pulling your credit score everytime they quote you a different vehicle

used Once your score is pulled, your agent should be able to quote you every vehicle out there if need be w/o calling for your credit score every single time. Sounds odd to me.
