Tell me about it. I went through somewhat similar antics with my ACR. In that case, speccing was really not an option, as most of the builds were already accounted for by a few dealers that had bought up most of the remaining build slots. At least, in *most* cases, by buying at the end of the production run, most of the bugs in the chassis have been worked out! But as is the case so often, production numbers seem to dwindle as the years go on, so that means fewer of the later production cars for 2nd hand buyers to choose from down the road, IE for those of us who could not get our hands on cars we wanted when new.
Nice choice on the specs. Are you opting for Cup2Rs?
