Pete,
Difficult question to answer. Having had a Series 2 and not a +8 it would be difficult to really comment on the downside when comparing the two.
I enjoyed owning the Series 2 and didn't really see a down side to ownership. Service costs were reasonable when compared with other cars of similar performance, mechanicals fairly bullet proof.
Not much help I afraid but its a start.
Do you have a car in mind?
