Drove the GXP yesterday and aside from both cars being front engined 2 seater roadsters they have nothing in common. NO power, SRT WAY faster. Clutch is difficult to modulate, rear suspension felt wallowy and the brakes had ZERO feel, like stepping on a brick. The steering had no feel and there is absolutely no storge space and much cheaper build quality.
I'm going to wait unitl after summer to buy my replacement roadster. Pay too much of a premium buying a convertible in April....
Thanks for all the comments except where this should have been posted
