Buick Century’s were NEVER fast.
86-87 Buick Regals with Turbos were fast.
Century’s were ALWAYS something 70 year olds bought.
I think they had a trim level that included turbo and for that reason budget guys buy them and tweak them up with exhaust, heads, cams etc. Upon first seeing them I recall wondering which in heck would turbo a Century.
Well, this 71 year old would still be driving a Porsche if I could afford it.
