Opel is a European manufacturer of cars and the parent of General Motors UK. It has a distribution deal with Buick allowing it to sell repackaged versions outside of the USA. In the UK it sells cars under the Vauxhall marquee like the Vectra, Astra and Corsa. These cars were the staple sedans and compacts in the UK in the '90s and still hold their value today thanks to their excellent build quality.
If you're looking for something a little different this time, consider adding a unique Opel diecast model to your collection.
