Pretty reliably cars the IS250's with an auto box.

Sticking calipers, corroded exhausts and wheels are the most common complaints. Carbon build up pops up as well so worth looking out for.

Add as well:

1. Windshield mouldings (I know minor) - replacement is ~£200. If lucky only need to replace clips which can be bought of eBay and alike for ~£15, but mouldings brakes itself quite often ~£80 each.
2. Corroded main grounding leads (more likely for wet climate) ~£600. Very hard to spot, most likely - hard cold morning starts when Battery is getting old.
3. If the windshield is cracked or was replaced possible issues with rain-sensing wipers and wiper defrosters.
4. Some cracking noises from central console or front speaker mounts are common if not fixed while new by the dealer.

Generally, very reliable cars if looked after. The only issues by design are the undersized brakes, upgrade from GS300/(US)IS350 is nice addition. Except, of that excellent cars.
