I'm not aware of any specific cases where someone has had a similar issue with an International Certificate for Motor Vehicles (ICMV) when traveling to Liechtenstein. However, if the make of the car on the ICMV does not match the information on the V5 document, it's possible that this could cause some confusion or delay at the border. It's a good idea to contact the DVLA to ask if this will be an issue, and if necessary, to request a corrected or reissued ICMV as soon as possible. It's also possible that the border officials in Liechtenstein may be understanding of a minor error on the ICMV, but it's best to be prepared and have all necessary documentation in order before traveling. As you noted, Liechtenstein may require the ICMV to control the volume of traffic entering the country, so it's important to comply with all regulations and requirements.
