You are entitled to your opinion. 100% support different views. However I have been doing acceleration runs most of my life. I have 180 runs over 200mph and most over 230. All of these runs have been in a controlled environment. No highway runs at high speed which i would say is a total bonehead move. When I see that stuff it drives me crazy. The runways ....that we use at any rate ....are checked for debris before runs/events. We are using military length runways that are 12-15,000 feet long and 200 feet wide. We don’t run side by side.....which is extraordinarily dangerous. In my progression through cars over the years some are better suited to high speeds than others. I had a viper that got “light” around 165. Felt like a boat coming on plane. Same with a supercharged Vette I used to have. There is a huge difference in cars that are made to go 200+ from the factory. They are incredibly stable at speed. All cars get a thorough tech inspection. The biggest key to speed runs is tires. You need properly rated tires with not only good tread but also no older than 5 years from manufacture. You would be shocked at what people will show up with at these types of events. That and braking. Going fast is great but stopping is key.
I did drive a friends Mustang GT350R at an event. It did 174 and it felt pretty good.
On the selling the games front I think they are different animals cars and pins. You will not do as well with a car....I have only had one appreciate which was my GT..... but there is something to be said for pure driving bliss. The 05 vette you mentioned is a great reliable fun car that you can’t really go wrong buying. Best performance for the dollar out there. Find a good example and you should be able to drive it for awhile and not lose too much on it. I am lucky I live where the weather is always good. My 458 is my daily driver and it doesn’t see downtime in the winter. Still I don’t think you would regret the purchase. But if you did you could sell it and convert it back to pins in a year or so and not be much worse for the wear. I would take the chance on the car. Better to live your dream than wonder in my opinion.
