March will be big, but I doubt much more than 2000 cars. So Europe won't get anywhere near those 5000 cars from Q4. Will be really interesting to see Q1 numbers a US sales also seem to be rather slow...

I think that your conclusion about deliveries during March is incorrect. In fact a vast majority of cars, for all regions, will be delivered in March because of the way Tesla currently schedules production. Below is an explanation of how I think this production allocation works and why deliveries in Q1 will be greatly back-loaded.
In order to meet quarterly goal while ramping production of MX, Tesla production allocation is currently designed to ensure that all cars produced during the Q1 are delivered in Q1. Given that delivery in US takes 1 to 2 weeks, delivery to Europe - 5 to 6 weeks, and even longer to Asia, production is scheduled to cover each region during specific time within the quarter to make sure that all cars reash customers in Q1.
In Q4 split of US/European/Asia-Pacific deliveries was 52% / 31% / 17%. Historically, out of 13 calendar weeks in each quarter the factory is running 12 weeks, with one week of down time per quarter for tooling. Roughly splitting 12 production weeks in above proportion results in 2 weeks of production (100% of it) allocated to Asia/Pacific, 4 weeks of production allocated to Europe and 6 weeks of production allocated to US.
In order to assure that all cars produced in Q1 are delivered in Q1, the last week of Q4 and first (working, or second calendar) week of Q1 - total of two weeks per the above - were allocated to producing cars exclusively for Asia/Pacific. Given 6-8 weeks for delivery this assures that all these cars will be delivered in Q1: second week of Q4 +6/8 = 8/10. This means that all cars slated for Asia/Pacific will be delivered between the 8th and 10th week of Q1, i.e. during first and second week of March.
The next four weeks are allocated to the production of European orders. This means that last European order will be produced during the 6th week of the Q1, which leaves up to 7 weeks for delivery of the cars produced at the end of 6th week of Q1. Once again this means that virtually all European cars will be delivered in March.
Finally, from the 7th through 12th (calendar) week of Q1 the production will be fully allocated to NA, with cars designated to CA being produced last. This again will result in majority of cars (roughly 2/3) delivered in March.
The net result of the above is that almost all cars destined to Asia/Pacific and Europe will be delivered in March, while about 2/3 of cars designated for NA will also be delivered in March.
The European cars that were delivered during Jan/Feb are essentially cars that were not delivered in Dec of 2015 for one or another reason.
Finally, during Q4 Tesla delivered about 17,400 cars, 208 of them MX. So total delivered MS were 17,192. At the same time, according to the shareholder letter Tesla produced 14,037 vehicles (with up to to 13,829 of them MS). Given that Tesla producing around 14,000 Model S per quarter, the Q4 goal of 16,000 vehicles likely includes 14,000 MS and 2,000 MX. So deliveries of MS in Q1 will be roughly 3,000 less than in Q4 of 2015.
Here is how deliveries in Q1 might look:
