I don't buy cars that were leased just like rent-a-cars.
That's a fine strategy, but know that you will exclude a large number of good NSXs in your search. Honda had some good lease deals on the NSX in the past, and many owners took advantage of that. In fact, my 92 was first leased by the original owner. Then, when the lease ran out, he bought the car. He only drove it 12K miles between 1992 and 2000.
So, a leased NSX isn't a bad NSX just because it was leased. Keep that in mind when you are searching and take your time (as you already plan to do). :smile:
