Modifying cars for what it is not intended for is not the best thing especially when it comes to reliability.
Bugatti means ultra-luxury and ground breaking super-fast sports car. It’s a car brand that Volkswagen invested to keep a big brand name alive. Critics with little common sense and engineering knowledge scoff at Bugatti costing so much money. Well it was not intended for the common people. It is an exclusive brand for exclusive people with deep pocket and appreciation of Bugatti’s history, design, and performance. Volkswagen spent billions of dollars in Research and Development to create the Veyron to be extremely reliable, ride like a Rolls Royce, and look glamorous.
What people fail to acknowledge, even pretty wealthy people with money to modify their Audi R8 and Lamborghini’s, making 200+ mph car is doable but it still requires a lot of MONEY. Underground Racing creates one of the best aftermarket products out there. They work great but there is a limit to where the lack of R&D will show.
