McLaren has three paths from which to choose; the sports series, super series, and ultimate series. Occasionally those lines are blurred though… like you’ll find with the McLaren 600LT.
This is the king of the sports series cars. Taking engineering know-how and parts gleaned from its bigger, badder siblings, the 600LT is grand tourer if your tours occur mostly on race tracks.
[Disclaimer: McLaren tossed me the keys to the 600LT and included a tank of fuel.]
