Seriously though, each has its merits.
The first Celica Supra was a great little car that featured some appointments that normally only came on more expensive cars. They're odd looking, and it's a shame more of them haven't survived. A straight 6 (pretty sure it was a 4M-E) was a pretty big engine for Japanese cars back then.
The Mark II (MA61) was a grown-up's GT car. Comfortable with lots of features, well built, but still sporty and fun. Journalists of the day raved about them. Well kept versions are hovering around $20k these days, and going up.
The third gen got big and heavy, thanks to all the technology and creature comforts that were added. But with a big turbo engine option helped it along well. The styling is just awesome.
The MKIV obviously is the famous one and everybody's favorite. Remember though this car had gotten very expensive. Inflation adjusted to 2023 dollars, a Supra Turbo in 1996 was around $90,000.
