It was able to get onto the trailer under it's own power, and I drove it to work the following Monday... it needed a water pump to be "driveable" but I ended up doing a few other things to the car. It was an old Geo Metro and I wanted one to tinker with. I spent about $600 getting the car like I wanted it.
We've spent 45k over 3 years between 4 people racing a fucking Saturn station wagon. Vast majority in travel and maintaining the $500 car. Goes up from there homie lol
Racing sims can get crazy. Full wrap around monitors, motion rigs, load cell pedals. You can buy all the same equipment that F1 racing teams use, provided you're willing to drop six figures.
That said, there's some top sim racers that have a Logitech wheel clamped to a desk.
