I have only had my GS 350 a few days yet driving it is an absolute pleasure. Acceleration is excellent, handling is very good, the seats are comfortable and the sound system is superb. However, the navi, Bluetooth and lack of XM radio are a disappointment. I owned two Acura TLs, the last being the TL Type S, both fine cars. However, I wanted a smooth ride, but still with some power. The GS 350 certainly fills that order. However, the navi system is inferior in every way to the Acura TL as is the Bluetooth operation. The Acura came with XM for free and if you want to install XM on the GS 350, it is an $850 charge. Despite the negatives, the positives are so many that it makes this car a joy
The appearance, performance, and comfort along with the great sound system.
Copy Acura's navi system and, for heaven's sake, allow changes while driving. Also, copy Acura's Bluetooth. The GS 350's Bluetooth is slow, repetitive and the sound does not come out of the speaker system. And, pop for XM radio, it should not be an upgrade. If Acura can do it, so should Lexus.
