To be clear these cars, any cars are foolish purchases. No-one in their right mind is buying someone that will be worth 30-50% less in a few years. This is an indulgence plain and simple. Yes Porsches and Ferraris depreciate slightly slower, but in the end it is a matter of supply and demand. When the model is new and the car is HOT prices are high and stable, a few years old is yesterdays news and there are deals to be had. I have found most McLaren dealers are very willing to work with customers and they do go out of their way to make the ownership of the cars a good experience. Get the best car that is within your budget. there are a few updates to the '18's vs the '17's that deal with the dash screen but all in all they are great cars. If you want the best of BOTH worlds, look for a 570GT with the Sport Package (570S brakes, suspension settings, and steering rack) basically a 570s with more luggage space. I bought mine from Miller Motorcars in September and it now has almost 3,000 miles on it. Every time I drive it I say WOW!
