OEM Automobile Systems - How do you rate them?

FWIW, the Infinity system in the Chrysler is actual a Delco with the Infinity named slapped on the front..

My Mercedes Bose CD changer (cost $995) broke after 14 months. Dealer said unfixable,uncovered by any warentee after a year, and that no other unit would work in the fiber optic system. Luckily my local electronic guru fixed for $100. BTW the sound is adequate at best.

The new Ford GT supercar: McIntosh

I own a Volkswagen GTI: Monsoon system sounds boomy but with the tone controls in action, it isn't too bad.

The DVD-Audio system in the Acura TL... Incredible (for a car system).

Don't own it, but spent about 45 minutes in a showroom listening to and was VERY impressed.

I should say that I currently own a 2001 Nissan Pathfinder with the Bose system. It was standard with the model I bought so I can't complain for the price and it sounds ALOT better than the base system that was available that year. I have heard the Mark Levinson systems in a Lexus and it did blow mine away, but I consider mine a low end Bose system (six speakers - four mid/bass, two tweeters). I know that their are some "higher-end" Bose systems (Cadillac STS, Infiniti M, others?) where they did the personalized surround sound that I haven't heard yet (hard to audition new car stereos from Afghanistan), but it seems to me to be an interesting concept.

I have also owned a Mistubishi 3000GT with a great Infinity sound system...nice and loud...of course I was just out of college and that was what I wanted in a system, and also drove a Plymouth Minivan with Infinity sound system (poor college folk) that sounded great at the time.

About myself:
I consider myself a low grade audiophile as far as my ear. I love sound...Movies are what I am really into. I currently have a Bose HT using the Acoustimass 10 Series III and Denon 3200 receiver mostly due to the size of my living room (my house is in Hawaii), but am looking at upgrading (I REALLY like what I am seeing out of the M&K S150 THX). My previous HT was using the Bose 10.2 Series II that I thought better portrayed the full range of the sounds, but they were TOO BIG for my room. I still have them as they got me through college very nicely, but they won't be playing anywhere soon...before you get too up on my Bose systems, I bought all of my Bose from Pawn shops or deep discounts except for the Acoustimass 10 I currently own, but I stand by it's purchase due to the limited space in my current room.

Sorry, got off on a tangent...

This is more pondering the next level of OEM car stereos that seem to be out there (THX, Dolby surround sound, etc). How are they rating with your more refined ears?
