 Upgraded from a 2010 Mazda Miata GT hardtop to my 2012 BMW 135i M Sport Convertible about 4 months ago, due to need for small back seat for kiddos and desire for a bit more hp and refinement than the Miata could provide. What a difference! Double the hp + tighter suspension equaled serious handling upgrade and BMW options/refinement make the car much more daily driver user friendly.  Surprisingly, the soft top is as quite as my SUV on the hwy and ten times quieter than the Miata's hardtop.  Tiny backseats are perfect for my small kids but are barely useable for normal adults.  Truck is more than adequate for grocery runs and can hold full size suitcases in a pinch. Outward visibility is great, top up or down.  Exhaust sounds awesome under acceleration but is quiet at cruising speeds.  M Sport package gives the car an aggressive appearance.  I do miss shifting the gears in the 6 spd. manual of the Miata but the DCT transmission of the BMW is a close approximation and is more wife/valet friendly.  Serious upgrade in costs for maintenance and repairs compared to the Miata, as well---not so thrilled about that!  Shopped around and compared a lot of cars but nothing combined the small car feel/driving experience with 4 person seating as this 1 series convertible.   Happy with my purchase and would highly recommend checking one out if you have similar needs for speed/space/refinement.
