You know what they say... if you can't buy it, build it.
It's also worth mentioning...
Many people, including myself, like the 80's Regal because of what they are, the car itself, not because they are fast.
Put it another way...
I have been into classic cars for over 20 years, I have owned close to 20 of them, 5 were G-bodys, 3 were Regals, 1 was a T-Type and 1 was a T.
I CAN afford to buy a Turbo Regal, but I don't want to buy one. There are several reasons... have no desire to go fast anymore, I feel the prices are too high for what it is, and so on.
Problem is, I still really like the 84-87 Buick Regal, the car itself, not because of the turbo engine. So if I don't want to go fast, and could care less about the turbo engine, why pay the price tag and suffer all the side effects that goes along with it? Just doesn't make sense.
That is why I decided to build my own Regal, with a V8, just like the Monte SS and 442, the way I want it.
