No, it has a timing chain.
The Lexus GS300 qualifies as a midsize sedan. This is a great car, and it has only improved with each new generation Lexus has released. Its latest design was in 2006; however, the 2006 model was discontinued after a year and then rereleased as the GS350. Lexus made the GS350 in a response to the consumer complaints about the lack of power in the GS300. The GS350 was released with a 3.5 Liter V6 engine. Both the GS300 and the GS350 are identical except for the beefed up engine. Hope this helps.
