I have driven all the trads (exept the Roadsters later than the S1), although only my own Roadster S1 extensively. I agree the Roadster is somewhat forgotten. It is more powerful than the +8, no cooling issues (at least if you have a brass rad), the point of gravity is further behind and thus the car better balanced, a very good gearbox (at least the S1 that has the Getrag, the later Ford Transit (?) box I have no experience with). It does not have the V8 blurb that I admit is somewhat addictive, and less torque - but more than enough. The more or less pronounced rev hang of the later Roadsters might or might not be an issue. In my opinion the early Roadsters are technically and performance-wise the best Morgan, at least if you are a cruiser. The lightweight 4/4 and +4 are more nimble and "chuckable" (and less expensive), I do admit that. But it is the iconic +8 that people dream about. All fine, these cars are not bought with the brain alone. The heart is much more important...
