Hi guys I'm looking to buy a Lexus IS200. (Current Car Ford Fiesta)

I've seen a 2004 Lexus IS200 SE 4DR

Metallic Silver colour

36,000 Miles

One Owner

Full Lexus History

They say it's a high spec model with park distance control
The price is 6,250

From the pictures and the information seems really good
but I have a a few questions.

I was wondering since the car is over 6 years but with low milleage, should I be worried if the timing belt hasn't been changed? And finally is the price reasonable?

Thanks :)
