If I had £200k to play with, a Cirrus would not be a priority - an Escapade and a Pitts S1S, with fuel, maintenance, insurance and hangarage (not to mention training) for 5 years would. Or maybe an MCR-01 with expenses for 10 years. I know a millionaire who'd go for the latter without a second's thought.
I agree with much of your comment. Whilst clearly the above paragraph is a personal view, I think it is also important to understand the reasons for the success of aircraft like the Cirrus. The comparison with home builds or Escapade is not valid any more than comparing a Caterham with a Porsche. Both might offer similar performance but that is the extent of the comparison. Cirrus offer an "executive" cabin for pilot and passengers, a "solid" aircraft with many other safety features (aside from the BP), and a sophistication of avionics, to name but a few of the features not offered elsewhere. Its the whole package that makes the product attractive to some, in the same way that there are those that prefer Porsches to Caterhams.
