It wasnt desupercharged. Its far simpler than that. The Spitfire used a Rolls-Royce Merlin rated at 1030hp, later models used a larger capacity engine derived from the Merlin called the Griffon producing upto 2340hp. There were a few other upgraded engines in between but the gist of it is at the beginning of th war it was 1030hp and by the end of the war it was 2340, there probably was at least 1 model around 1700hp in the middle of that. The 2340hp variant was a fucking quick plane for the time, it wasn't the most agile though as the larger engine weighed alot more and the airframe was only originally designed for the lighter 1030hp engine, it could still out maneuver any german fighter though. This car did not use either the merlin or griffon engines. It actually used a bog standard factory specced Rolls-Royce Meteor engine. The Meteor was pretty much just the merlin engine without a supercharger and adapted for tank use though so you are close. But the car did not take a spitfire engine and remove the supercharger, they took a factory produced non supercharged version from a tank.
The TLX has a pretty nice interior. That's one of the selling points to me over its competitors. The BMW has a nice interior. But the best but more expensive would probably be Audi. I don't make much so the TLX is the maximum I could even think to afford right now. It provides plenty of luxury and sport to me.
Seeing as we're on the topic of S30's: (imported from here) (imported from here) (imported from here) The S30 is certainly a beautiful shape, I would not hesitate to say it's far better looking than many other sports cars of the time i.e E-Type
