The F136 can be found in the Ferrari F430 and California, the Alfa 8C, and Maserati models dating back to 2002. This includes the often-daily-driven-by-pretentious-fools Quattroporte, lending credence to its reliability, but if you want the real deal step up and pull one out of a 458.
That said, the Grand National is one of the best factory sleepers ever made and you should be able to find one of these crazy cheap cars for around $20k, even though the average asking price seems to be MUCH higher.
The 2019 Buick Regal Sportback doesn’t only bring new styling to the table. The new car is also larger and up to 500 pounds lighter than the fifth-generation models. It’s powered by a sporty 2.0L turbocharged 4-cylinder engine which makes 250 horsepower. It also develops 260 lb-ft or 295 lb-ft of torque if equipped with front- or all-wheel drive respectively. The former is fitted with a 9-speed automatic transmission while the latter comes with an 8-speed auto.
If you want to do this, read about what it takes to shoehorn one of these used engines into a Fiero. Spoiler alert: it’s not a lot. Everyone talks about the larger Cummins used engines, but what about the four-cylinder 4BT? The “baby Cummins” will allow you stick one of those crude stickers on any car you want. Turns out not everybody knows what those stickers mean, so follow that link to get learnt. I’ll wait.
