The Car Connection's Take
TCC Rating

7.6
TCC’s Bottom Line
The Infiniti G37 Convertible doesn't suffer the usual styling compromises, but it's a little less exciting to drive than its Coupe cousin. The 2012 Lexus IS 250C strikes a good middle ground between racy roadsters and luxury convertible cruisers, but its sluggish powertrain performance will be a deal-breaker for many.
