The LS series is now in its 4th generation. The first generation was sold from 1989 until 1994. It had a 4 speed automatic transmission paired with a 4.0 liter V8 engine. With a top speed of 155 miles per hour, it was faster than any other luxury sedan of the time. The LS 400 was the first Lexus car to be sold in the United States. Car magazines tested the car against the established luxury brands such as BMW, Mercedes Benz, Jaguar, and Cadillac, and the Lexus knocked the socks off of all of them.

The first generation sold very well, with over 20,000 cars or more sold each year at a price of $35,000 and up.

The second generation was sold from 1995 to 2000. A 5 speed automatic transmission was added as an alternate to the 4 speed on some models, but the online engine once again was the V8. Some critics suggested that the new model was too much like the original. Sales were still good despite this, as the Lexus was still priced thousands less than the competition.

The third generation, sold from 2001 until 2006, got upgraded transmission options with a 5 speed or 6 speed automatic. The LS 430 would be the new model introduced with this generation. It featured a 4.3 liter V8 engine. It received sparkling reviews. The car was redesigned in 2004 with better performance; it could now do 0 to 60 in 5.9 seconds.

The fourth generation saw the introduction of two new models: the LS 460 and LS 460 L. These cars had their debut in 2007. The L in the latter model stands for long wheelbase. What's most amazing about these models is the transmission: an 8 speed automatic. The longer wheelbase model sells for $71,000.

A new LS 600h is a hybrid luxury car that sells for over $100,000. It produces 438 horsepower and has all wheel drive.

LS series cars, especially the early models, can be found out there on the used car market, but you probably won't find any at a seedy used car dealer lot. Try checking on places like eBay, where sellers think, often incorrectly, that they can target a more affluent market.
