Yes, you have been caught!!
A bit of additional information: Don't know how deep your budget is but the new Plus 8s, from 2012, have a wider cockpit, by about 15cm, and more adjustment on both seat and steering column. The Column is from BMW and adjusts both up and down and in and out!!
But a 4.8L BMW V8 may be a bit costly to tax in the Netherlands...
