Best track car 5K budget

[Robonhoms]

Im looking for a preferably rwd track car for under 5K for everything. I have limited mechanical knowledge but would hopefully use this to help me learn. I can have access to professional garage equipment but not all the time. I have looked at mazda mx5, mk2 toyota mr2, clio sport etc. Also looked into cheaper kit cars but feel this might be out of my depth. I also have garage space but only really for smaller cars so things like e36 wouldnt fit. I would prefer to trailer the car so would not need to tax and insure. What would be a good car for me based on these things?
