I recommend you register your car on the Lexus website service section (hope that makes sense). You'll need the lig book first though because you'll need a number from it. Once registered you'll be able to see the cars service history if its been done by Lexus. Its really good. Good to know you researched the is250. Brake caliper slide pins seem to be an issue. Its one thing Lexus don't look at when servicing (except if asked for). There's loads of info on here regarding all aspects of the car. If you fancy adding Bluetooth streaming capability then search it as I've done a post on it and answered others. As for a front spoiler. You have the f-sport so I think you have a bumper lip already but there are alternatives out there. Look on ebay. There's been a few on here done mods. Look up those threads as I'm sure you'll get links too. I know what you mean regarding CVT. My first is300h I loved initially but within weeks I hated it mind you I came from 25 years of manual gearboxes. Swapped it for the ecoboost mondeo then back to the is300h and loved it all the time I had it,even the RX450h I part exchanged it for.
