I traded in an 06 Audi A-4 Convert, 1.8T. I hated the turbo and paying prem fuel for 170 hp. My previous car was a '99 Boxster and I loved it, but it became a maint nightmare ($3200in 4 mons.) I was on verge of buying a new Boxster and decided to test-drive the SK (I had already driven Z-4, 350zx, S2000, TT, etc). I got a great deal ($6k off msrp) on SLK & 100% sure of decision. Boxster has great style but doesnt't have 7 spd automatic, hardtop convert, heated 'scarf', etc.
7 spd automatic, heated neck 'scarf,' Sirrius radio, TeleAid, roadside asst for as long as own vehicle, self- dimming outide mirror.
