I tried to upload pics but I can't seem to do it at the moment. Anyway here are some impressions.
First impression of it is very good. The major flaw is the body, as you will see in some of the pics. The hood is pretty chipped up with rust showing through; not sure if it's worth getting it painted just yet. I suppose the guy must have driven a lot in rough terrain or on long highway trips. The interior is nice. The leather seats are not at all glossy, but a nice matte (as they should be from what I read). On the drive, the car is really smooth; both the engine and suspension. The seats however do not hold you well even in moderate lateral loads, but they're powered/heated and comfortable. It has decent pickup in 1st and 2nd (though I only went up to 3.5k rpm). I like the lighting of the Lexus instrument panels, they have a nice glow.
In the last couple months the previous owner changed: oil, spark plugs, coolant, brake fluid, all brakes (including rotors I think), and a rusted out heat-shield. That bill was $1.5k. The timing belt was changed at 122k km, so it should have another 80k km before we do it again.
I read on the web about Toyota's infamous oil sludge problems. They extended the engine warranty to 8 years due to this problem. I'll be making sure that my dad takes it in for a change every 8k km as recommended. Ideally it should be at the dealer (~$50 with some other BS inspections) so they have records of it and can't dispute anything if something were to go wrong. On a similar note, for some reason the records from the dealer show that they put 5W20 while the owner's manual states 5 or 10 W30 (depending on weather). Maybe this is something to due with the sludge problems??
