I have just Sold my Big single Supra and took an Evo 9 Wagon in exchange, The Evo is of course more modern feeling to drive but the interior is very disappointing, however the Supras interior is looking dated now compared to modern cars. The Evo is far more planted but the Supra if driven well is a fairly predictable car, inexperience or over excitement causes most incidents (or diesel)
A big single Supra is a blast to drive and is still a force to be reckoned with, even by modern standards, it is however expensive to run, maintain and insure and with the prices going through the roof they are no longer a cheap base for power
Also worth thinking about the cost and availability of OEM parts as the time goes by, they will become harder to maintain in the future
I am sure if you were to get a ride in a single you would forget about all the above and want one, but take it from someone who has had a few, they can be a BIG money pit if you get carried away with them
