When I bought my car almost a year ago, I was happy it came with the window sticker! Back in 1985, my 300CD was listed at $35,220, and EPA fuel economy rated at 22 city/25 highway
Best I've gotten is around 30mpg I believe. Also, it sold new at Overseas Motors Corporation in Ft. Myers, Fl. Hope you can locate your ideal cost of your car..
