I was wondering if anyone could point me in the right direction of a website or guide of new vehicle prices in USD, going back until at least the early 90's. I am doing a little research project and want to look at the increase in cost of new cars in the US compared to inflation, salaries, etc., etc over the past couple decades.

I just need base MSPR, no add ons or anything to add more variables. Any help or general suggestions are appreciated, enjoy the 930 slantnose
