Buick Regal: generations, engines and what to know when buying used
The Buick Regal is an American mid-size sedan whose newer generations are technically close to the Opel Insignia sold in Europe. Here, we review the 2011–2017 and 2017–2020 generations, engines, and what to check when buying a used car.
The Regal in brief
The Regal is Buick's mid-size sedan, with newer versions also offering the TourX wagon. It is not officially sold in Europe, so in Lithuania, you mostly encounter cars imported from the USA or China.
Buyers are drawn to the more luxurious interior than a typical sedan, quiet ride, and relatively low price compared to German competitors.
Which generation to choose
The 2011–2017 generation is based on the platform of the Opel Insignia sold in Europe at the time. It is quite spacious and comfortable, but part of its construction is aging, and the engine selection is narrower.
The 2017–2020 generation is built on a newer Insignia platform: the car is lighter, more modern, with better multimedia and safety systems. It is available with the Sportback sedan body and the TourX wagon. If the budget allows, it's better to choose this generation.
Engines and transmissions
The Regal was sold with four-cylinder petrol engines, including turbocharged ones. The sportiest Regal GS version of the newer generation has a 3.6-litre V6 engine and all-wheel drive.
Transmissions are usually automatic, ranging from six to eight speeds, with some versions featuring a manual option. Diesel engines were not offered for the US market.
What to check when buying a used Regal
Since the car is imported, it's essential to check its history via the VIN, mileage, and any accident records. Ensure the car is properly registered and that its headlights and other parts meet European standards.
Test the automatic transmission — it should shift smoothly without any hesitation. Check the turbocharger operation, cooling system, and look for any oil leaks.
Finding parts in Europe might be trickier, although the technology is similar to the Opel Insignia, so some parts can be sourced through that model. Always double-check that the part you need fits your specific car.
