Although the experts at TheCarConnection.com find the styling middling at best, most reviewers consider the 2008 Lexus SC 430 a sleek hardtop roadster.
This was the assessment of Family Car, which says, "Top up or top down, this car gets you noticed." ForbesAutos agrees, saying the SC Lexus "probably draws the most attention in traffic or parked on the street, thanks to its curvaceous styling and power-retractable hardtop." Cars.com is fairly neutral on the subject, but describes the "low roofline" as having a "sleek profile" (presumably when the top is up). Kelley Blue Book does acknowledge that "the SC 430's exterior styling won't please everyone."
It should be noted that the Lexus SC 430 has undergone very few styling changes since the model was first introduced in 2002. Edmunds--which also has little to say about this 2008 Lexus's outward design--does note that it was "one of the first modern production vehicles to popularize a retractable hardtop design."
All Lexus SC 430s feature "natural leather and wood" inside, according to Cars.com. In general, Kelley Blue Book praises the SC 430's interior, with its "loads of Walnut or Bird's-eye maple and brushed aluminum and chrome accenting," but they also say "the instrument panel's center stack is slightly busy, style-wise."
