I bought my 2003 SC430 with 50k miles on it for $20,000. Everything is immaculate on this car, always serviced when needed. The drive does have that sport car ride to it due to the low profile RFT's. The sound system sounds amazing although it is very expensive to replace just 1 speaker at $320. The rear seats (golf bag holder) are useless for people to sit in. The trunk surprisingly does have decent space when the top is up. Being that the model is still the same as of 2010. I will upgrade some of the standard parts to the newest style.
Hard Top Convertible & Mark Levinson sound system.
Upgrade to the LED tail lights, Install the new 9.1 navigation software & install K&N air filter.
