I have a little over 8k miles on my F. Not one problem thus far, but a too small of a sample to know reliability. My first impression is that it will be little or no different than any of the other Lexus vehicles.
2. Purchased not leased so no comment
3. PS2s are "stickier" than Potenzas, but I would suspect that the Potenzas will last longer. The 25 Fs at the Lexus Performance Driving Academy in Atlanta last weekend were on PS2s and the Michellin (sp?) rep was there pimping the PS2s. Unless you are racing I don't see any need for wider tires.
The only way I have found to really light up the rear tires on acceleration is to totally turn off the VDIM and Traction Control, power break and then launch.
4. Gas mileage. I have averaged 20.1 mpg since new. Much of my driving is on Houston's Beltway 8. I have averaged 21+ mpg for the last 5-6 tanks of gas. I don't "stand on it" all of the time, but I don't hesitate to go WOT at least 3-4 times each day. One of the other members just drove his from Houston to Colorado and claims he got 29.5 on the trip. (See his post yesterday).
Good luck on making your decision.
