It's all personal opinion, and what you're going to use your car for. Nothing wrong with a GSR - still puts most other 4 cylinder cars to shame. I really enjoy my R, but there have been times, such as when I'm driving 4+ hoursin marginal weather on the highway, when I would have enjoyed a Cadillac, for chrissakes. However, as soon as I get on a secondary road.......
It's not just the R's speed, or even it's ability to handle curves. I'm quite spoiled by it's level of braking performance/feel, it's general steering precision, how well it's damped despite it's handling capabilities, how 'tight' it is. It will likely be a hard and unfortunately expensive car to replace.
