Stylish. Average MPG 11. Cheap vinyl visors. Sits low, getting in/out hard. Average quality leather. Terrible navigation. Command system is technology from 80's Radio Shack computers. Outdated 6-cd changer. Unless you keep A/C on auto (which gets loud) awful mildew smell emits from inside car--unevaporated H2O in pump system. Some things don't work from 1st day like cupholder. Porsche & BMW = better handling but SL550 better than SC430. Interior leather & wood & ergonomics are better in Lexus by far! but are better than 911 & 650i. Sound system: 1=sc430, 2=BMW & Infiniti, 3=911 & SL550. Build quality sub-par, very bad. You buy this car for sense of prestige not because it's the best- it's not
Glass roof (panorama)--Cheap, flimsy sunscreen though. Fast (16 sec) convertible hardtop--can't drive while operating it like Porsche 911 & BMW 650. 12 posititon, Ventilated seats w/massage. Tiny compartment underseats for storage. Trunk closer button. Groove on gas-lid for gas-cap. Good windscreen.
1.) Change Navigation to the one used in Lexus & new Jaguar (touch screen). Theirs show names of every street and is intuitive and plain easy to use. 2.) Get a better sound system or at least use larger woofers and put speakers in the tiny back area. Also, could add a tweeter on windshield pillar.
