Can you post the prices on this 190E - base and options? Does it include "additional dealer markup"? The NADA Guide gives the original base price for each model, and the 190E options of that era would have included leather interior, metallic paint, power seats, heated seats, and orthopedic seats. I can't think of any other OEM options options.
I can't imagine anyone paying $45K for a four-cylinder 190E in '92. The base price of a Lexus LS400 was $42,200.
