jcanni,
I browse audizine regularly and here are a few options i would consider.
Take the 17.5 for your b5, and down payment on a low mileage b6. I know you can do in the 25k range for a b6 with 40k or so.
are you stage 2- now?? How much would it cost to upgrade to k04s???
If it were personally me...I would save for a 135i. Thats just me....sexy fast car. Owns e36m3.
Btw what are specs on your car? mileage mantinence?
Hope I gave some options.
hell yea. i want a 911 too, hahaha
