I purchased 07 GS350 in 09, now at 60K. Like the car a lot.
Good performance, sleek looking, much quieter and smoother ride with Michelins, dumped the run flats.
Added IPOD hookup which works great. Had dashboard rattles, brought back to two different dealers before rattles were entirely eliminated.
Pros; I find the car to be very comfortable, solid performance and handling.
Cons; Little more wind noise than I expect, especially around sun roof. Cassette deck vs IPOD hookup?.
NAV system can not be used while car in motion.
Performance, style, reliability.
Replace run flats, more noise insulation around sun roof.
