What is the average markup on new vehicles? I am specifically looking at a Lexus IS-250.

Please visit the following website:

New car prices, used car pricing, auto reviews by Edmunds car buying guide

They will give you the MSRP and the True Value of the car, on a side by side comparison.

not sure about markup. I can tell you a new car is financially a bad idea... unless you are wealthy and can pay cash. No payments. New cars lose 60% of value in 4 years... all cars. The brand don't matter.

auto dealers make most of their money in the shop and the finance office, not on the sale of new cars.
