YOU know you are being looked after when a full-size alloy spare wheel is located under the boot floor, along with a beautifully presented plastic tray for the tools, a first-aid kit and a valet pack with items to make the tyre-changing process more appealing - gloves, towel, handwash and a mat. (Alas, a blow-up mechanic is not included.) The IS300 is fitted standard with 7JJ x 17-inch five-spoke polished alloy wheels and low-profile 215/45Z R17 Bridgestone Potenza RE040 tyres.
