since you will track the car, it will get rock chip, possibly small/large dents. insurance may not cover damages occurred on tracks.
consider an used Miata (there’s a large online presence of miata racers and support) and use spared funds for consumables and safety equipments.[/quote]

I have an old miata. But I don’t feel that safe in a old miata on a road course, and spending money to make it safe for a road course would defeat the purpose of it being “cheap”
