I wouldn't want to drive my race car to the track, even though it is only an hour drive. It has been well worth buying an SUV and trailer, just because I can bring all my tools and tires, and how comfortable the drive is. The race car is just too loud and stiff, and with no A/C or heat, it's not something I want to drive home tired from a day of racing.
Another option that hasn't been mentioned, is you can often rent garage space at the track. I know people that do this and even share space to lower the cost. You would have to get the car towed, or rent a truck and trailer if you need to take it somewhere, but you shouldn't need to do that very often. I don't think anything could be easier than leaving the car and tools at the track at the end of the day. Since you live close, I don't think it would be a big deal to have to drive to the track when you need to work on the car.
