I do know that European countries have to be strict. Ever since the reunification/glasnost, there would have been an influx of a number of unsafe cars from ex-soviet state republics. They made the rules strict to keep potential disasters off their high speed highways. Once you make a rule, you have to stick by it for all vehicles. Classic American vehicles are tolerated as long as you don't make modifications from the original design. In a lot of ways this makes good sense.
I would look for businesses in that country that has had success in providing upgrades and retrofits.
