Bought our jet black '03 with 23,750 mi. on it (our 5th sports car, out 1st BMW). 2.5L eng, Premium and conven. packages, auto trans, 18" ellipsis wheels w/RFTs. Handles well. Electric steering so it gives no feedback thru steering wheel. Accelerates well, esp between 45 and 80. Seat bottoms aren't very comfortable after 45 min. Less interior storage space than a Miata. Roomy trunk for a sports car (no spare tire w/RFT pkg). Electronic displays are hard to read in daylight. Dynamic Stability Control necessitates alignments being performed by dealer - $90. Dealer oil changes are $90. Beautiful car that draws lots of attention from other drivers and pedestrians. Shrinking violets need not apply!
Handling (DSC), exterior styling, sound system. Did I mention the exterior styling? :)
More comfortable seat bottoms, improve visibility of electronic displays- especially the radio, mechanical steering, more interior storage space, lockable console.
