You can easily cancel and reorder and the only loss(es) are the $2500 USD per order. With so many cars, you are obviously of "some wealth" and such a loss is possibly not that much overall. The rules are in place and as the company grows, it cannot be "friendly" even to repeat customers. They have no dealerships to "work deals" with customers. It may become more black and white as more customers come on board. Without dealerships (and Jerome is not the "dealer" to work things out with) - I think you are basically making a "deal" with a computer-based policy management system and a set of rules that everyone is bound-to. Think of Tesla as a very large vending machine. The OP is wanting Tesla to "work a deal that I would like to see happen - because I am loyal and got friends to buy". That is favoritism, at least and requires finances within each currency to have hedges in place based on expected orders in place. Tesla has done big hedges before (the convertible bonds, specifically) - but more hedging to keep customers in every country satisfied for every movement in ForEx? It can go on and on. Modern business is, of-course, based on friend-sourcing and favoritism, but I have to wonder if Tesla should conform to that or is "busting the norm" and trying to get around the problems inherent to dealerships and other normal business practices.
What about when Model 3 comes out and Forex comes into play for customer orders and they have to "satisfy" 20,000 European and Asian orders per month or some such number. ForEx and order backlog might grow to 6-months or more, maybe a year. They will need to figure out how to do that well.
I live in a world of "contracts are contracts". I am stunned that Tesla has let people cancel orders for cars that made it all the way to the delivery site. Then they have sold them for discounts after using them for demo cars for a few months. Tesla has spent a lot of money trying to "satisfy customers". In Q4, some discounts were very large. I think it should be graduated. Cancel after 2 weeks but before build - $2500. Cancel after Build but before car shipped from Fremont - $5000. Cancel after Build when car at sales site - $8000. Or, in other words - consider an $8000 reservation fee, then a slowly declining refund value.
In general, Tesla must face the problems inherent to a rising USD valuation. This is a much bigger corporate issue for the company than upsetting one particular Swiss buyer. Consider that by the time the GF is built - there is a possibility that USD/Yen valuation may indicate it would still be cheaper to build cells in Japan.
