Hi GrumpyBastard, (Hey my wife calls me that too!) You can start off with the base Station Wagon or Fieldmaster or Trialmaster and then you can add and subtract almost every option to make almost identical vehicles. There are however a few things you can't change. if you choose the Trialmaster, you can not delete the raised air intake or if you choose the Fieldmaster you have no wheel/rim choices at all except for the one alloy choice they show. If your looking to keep the price down, then perhaps start with the Station Wagon and just add the few things most important to you. If you want more items, then perhaps pick either the Fieldmaster or the Trialmaster and add and subtract options to fit your need. If you are trying to decide between having a second battery or premium sound, I would choose the second battery as it is much easier to add a
sub-woofer later than to try and add the second battery later. If you choose the Station Wagon you will not get the free, (nothings free), Belstaff Jacket that comes for free with the Fieldmaster and Trailmaster. Not sure I will be wearing it much in sunny California. I think everyone agrees that it is fantastic that Ineos set it up that no matter where you start with any of the 3 builds, you can end up with any one of them being virtually identical. All US vehicles only have the Petrol engine. For me I choose the Trialmaster with most options, however will likely pull off the raised air intake and put a blanking plate on it. For me, the one must have are the Safari Windows as they are Cool & Bitchin, (I am dating myself here, however I have earned it at 71).
Have fun on their configurator.
