The engine was completely rebuilt by the Lexus dealership about 8,000 miles ago (currently has 128,000 miles) at Lindsay Lexus in Alexandria. (Previous owner is the manager of the dealership). The car runs suprisingly well, for having only 150 HP (i believe it's 150?), but i'm sure a few small engine mods would do no harm at all. One thing i did notice is that, while the redline is at 6500 RPM, i cruise at a very high RPM (about 3,000 at 70 MPH) which seems to me that would make the car use a lot of gas. Maybe because the car was sitting in the driveway until yesterday mid afternoon, that the engine was running rich and just using a lot of gas. I do use the gas agressively sometimes, but when i saw that i only got 50 odd miles on a quarter of a tank, it's starting to bother me, especially with gas prices.
As for oil, my dad tells me that you can easily go 5,000 miles on a single oil change, but that seems a little outrageous to me, if i want to keep it at its maximum performance and durability levels. I hear that Mobil 1 synthetic is one of the best oils out there.
As for tires, about 2,000 miles ago, a new set of Aquatreads were put on it, and the seem to perform decently when it comes to wet and dry weather traction.
Thanks for all the suggestions; i will start looking soon for that strut brace since i notice some bodyroll when cornering- maybe this will aid the problem somewhat.
:D
