Okay how about driving around Fujimi Kaido in stock v8 cars.
Rules are you can put a V8 in a car if you want to but you are not allowed to tune the engine.
If the car has a v8 in stock form and you have another engine as an upgrade its fine as long as its a v8 and you don't tune it.
Some nice cars, the Mclaren is brilliant and the new Cadillac is great for drifting. But other than that it's mostly small hatchbacks, some nice ones though, including the Colt which I easily got over 200mph out of, tuned up to R3.
