i usually go every year. but only when i have 500$ at my disposal as thats what i usually spend there, planned or not.
theres alot of junk you have to walk by before you find what your looking for because its huge.
good deals on exhaust, tires, wheels, body panels, headlights, ...watch out for the cd players tho, alot of them are broken and shop repaired and wont last long after you buy them. all kinds of stuff there.
