Just for clarification, I did not "save" 100k and was carefull not to use that word. That money is available only for housing and from an outside source (someone other than myself). I have spent nearly that much however on car toys since I graduated at 21 years old. Reading sites like these has brought me to the light of how stupid and wasteful I've been. Changing my car spending habits is just one of many financial changes I need to make.
Reading your comments, which are incredibly helpful by the way, is making me want to get a cheaper more reliable car. Such as, not to make the same mistakes of yesterday. Also, don't bother being so descriptive in automotive terms, I was an automotive engineer for the last two years (aerospace now $$$ :)).
Like i said, Audi's aren't known for reliability. Think of them being overpriced VW's. Your best bet is to stay with something inexpensive and reliable new. You should then get rid of your clunker too, as you don't need the extra insurance payments.
I have to say, jumping on an audi now is continuing down your trend of expensive car purchases. Look, wait until you make more money or come across a fortune. While an audi is nice, it's not worth wrecking your finances over. I had my beater for 7 years. And my audi is currently on track to a beater for 10 years.
