HMMM your all scaring me now. I just brought a 2007 GS 350 off lease. Funny thing is that no one every deleted the phone book so today when I bonded my phone I saw all the old numbers. I was tempted to call the previous owners home number and see how they liked the car, but I found this forum so no need to freak them out like that!!!!
Anyway I just got rid of a 2006 A4 2.0T. It was fun, has a great german ride for sure. But the issues were killing me!!! I cruised through the 50K coverage about 50K ago. I was up for a timing belt and my third set of tire.
The main issue for me was:
Coolant leak, not coming from the reservoir or the bleeder tube so that was going to be $$ to fix
Miss firing... I had the car back to two Audi dealers 3 times for misfiring in the engine. Initial starts the engine would pulse and stutter for the first 15 minutes. Then after that you could feel it on acceleration in the 2K-3K RPM range while you were shifting it felt like the engine was out of balance.
Good luck on the MB. We went the MB route but that was in the 2000 and it was also plagued with Chryslerish issues and the style changes every 2 years that they look out of date quick...
Got my fingers crossed for the GS it has 30,000 miles on it now so I was interested in reliability based on my Audi experience. Had the Audi been reliable I would still have it. It is an excellent ride, excellent handling, and great in the Snow.
I just got a ES350. The dealer had a driver pick me up for the delivery in a GS350; I thought the GS was really nice and since the ES350 column is quiet I looked over here and saw this thread.
The ES will replace my 2003 Audi A4 1.8T Frontrak. The Audi (with 85,000 miles) has a great radio, incredible seats, is almost as quiet as the Lexus, and great steering feel (although new ones are electric steering and numb). The downside was replacing the rear window because the antenna never did work if the rear defroster was on, replacing the windshield wiper rack (I was lucky, only $350) and then the computer system on the transmission failed ($2,300). A windshield washer needs to be fixed ($600), the rear window lock control needs to be fixed ($?), it will need a 3rd set of tires soon and I don't think the timing belt will make it to the suggested 105,000 miles before it needs to be replaced. There is a persistent rattle in the overhead console (already paid $150 to get that fixed once). Oh yeah, it is starting to use oil. Love to drive the car; tired of putting money in it. I would loved to have gotten another Audi but I just don't feel they have a shot at going high mileage without relentless repair bills.
My Mercedes ML320 was worse. Just as bad as its reputation suggests. Although the seats were also wonderful; 5 hours at a time was no problem. However, the dealer had the attitude that repair bills were part of the MB experience/mystique.
No, Lexus isn't perfect and unfortunately the GS seems to be causing growing pains for Lexus. However, I do not know any MB, BMW or Audi owners that go over 100,000 miles unless they put a lot of money into their cars. And yet, it isn't that hard to find Lexus owners who do. I'm hoping my ES is one of the good ones. Also hoping the GS improves.
