Be patient keep the camry for a year or two save money then spend up big on a bigger and better car.
I got my rona just on two years ago now, i have bought tyres shocks and springs for it and general maintenance and thats it, it now corners decently and being lighter and having cubes on it side would be a bit quicker than your camry but that another story.
Instead of wasting shitloads of money in the time i have had it, (modding a 22re is a hiding to nowhere)i opened an ING saving account and have been putting money in it monthly. MInd you i now work fulltime after finishing school don't no what your sitch is but money is pretty good for me atm.
I will be looking at getting a car around the 20 mark by the end of the year and will pay atleast half of this in cash.
