I recently tested a Z4 3.0. It's 67k cdn for the 3.0 but only 54k for the 2.5. The thing is only the 3.0 comes with SMG but i'd rather pay less for the 2.5. Hard to justify the 13k more for a few more ponies and options like SMG. Should I ante up and get the SMG 3.0 or play it cheap and get a 2.5 with s-s-s-slow steptronic. I had a e46 328i before with steptronic and the slowness of the shifting was uncanny. Meh, was at a Porsche dealer earlier with a buddy when he went to get his Cayenne and I saw some used 996 Porsches from '99 for 65-70k with options. Awfully tempting too. Cliff notes: Just want a cruising car...but who doesn't want more ponies? Question is justifying the increase in cost.
