I've owned a '98 LS400 for many years, and do much of the routine maintenance myself. For other things, I go to a fine independent shop and avoid the dealerships (with reason). You might consider reading one or more of the very good forums on line for owners.

Oil and filter changes are easy to do yourself at about 5000 mile intervals (not 3000, that's a real waste). And I never use synthetics. Unless you tow a trailer in the desert with the car, you don't need them either.

The alternators are not intrinsically bad, but their locations are. The alternator is below the power steering pump, and leaking fluid (they have a tendency to leak) can drip onto the alternator, causing it to fail. So keep an eye on your PS fluid reservoir. If you get a small leak, try Lucas PS leak stopper. It often works very well.

Wal-Mart sells excellent batteries for the car... believe it or not!

If you lose a transponder key, you can replace it from an Ebay merchant very cheaply. The car actually programs it. Dealers will tell you that only they can make them. It's one of their lies.

The brake pads are almost child's play to change, especially if you have Brembo brakes. Aftermarket pads such as Wagner are excellent. Replacement rotors are often cheaper than having the old ones "turned" on a lathe. Get a brand name product at a fraction of dealer prices.

Tires? I like Sumitomos, but lots of others are suitable as well. I do not follow the recommended pressures, but just use 32 psi all around for better handling.

Lots more, I guess. Ask any specific questions you have. You'll love the car!
