Hi all -
Once again, need your humble opinion. The lease is ending on my 09 35i. (babied..only 10K miles
After test driving few other cars (inlcuding the current M3 conv) I decided to stick with z4.
I'm wondering if it makes sense to order a 35i (with sport pack) and then get a dinan upgrade OR get 35is.
Once you get the sport pack on 35i there is not much difference (to 35is) besides the power. The difference between 35is and i is almost $10K, which gives you only +35hp
Does it make sense to get 35i and Dinan? Any warranty issues ? Thanks...
