Who said anything about outright speed? It should be well balanced so that a good pursuit driver can make progress, and it needs to not be French and fall apart. A 335i with a few options (not sure where you get the idea that they fully-load them from) is a much better bet financially too, as although it costs twice as much as other choices it loses less when it comes to sell.
Truth is, if everybody stopped speeding in silly places then they wouldn't bother targeting folks. If you speed in places where the cops can sit and catch you with ease, then you're part of the problem. Well, not you specifically Aidan, but you know what I mean.
