The comfort of the interior, the quality of the sound system, the smoothness and quietness of the ride even with the top down.
Love the car! Everyone watches the hardtop retract and ooh's and aah's! They all refer to it as a real transformer! The car is beautiful inside and out! It takes about 30 seconds to raise/lower the top. I was worried about acceleration due to the extra weight of the retractable hard top... but it's not too bad! This is NOT a GT Mustang - if it's strictly performance you want, this is not the car. If you are looking for a refined, luxurious drop top though - this car is perfect. It has a nice, smooth ride. Gas mileage is ok. Plan on the extra costs for premium gas The upgraded stereo with subwoofer is very nice, as well as MP3 connectivity and Satellite Radio. Mine also has the GPS which is very nice as well. Highly recommended!
I am a big believer in listening to owner feedback. Based on the leading consumer magazine, I narrowed my search for a hardtop luxury convertible that seats 4, down to the BMW 3 series and the Volvo C70. With the Volvo some $6-8k less w similar equipment, it was a no brainer. I could not be happier with my choice of the Volvo. The Volvo C70 is a beauty, esp w/ the top down, and it has run flawlessly. There is plenty of room in the back seat for 2 adults, but it is much easier to get into the back w/ the top down. I highly recommend the Dynaudio radio upgrade, as it is amazing! The C70 seats are like sitting in a nice Lazy Boy recliner and I find the ride smooth (although other report it a bit stiff). The engine is powerful at higher RPMs, but there is a distinct turbo lag off the start with auto automatic transmission until you accelerate a bit. I commute 50+ miles a day and wanted a comfortable car for the drive - the C70 has proven a great choice. All convertibles flex some - and mine has developed a slight squeak in the right rear window after 10k miles. If you are looking for a comfortable, quality built convertible with great safety features (Volvo is the leader in safety), that is fun to drive - here it is... the Volvo C70.
