What are you looking for in your car? You could do small things with 1k$ to make it look nice, you could look for used tire/rims in other classifieds for i bet 500$ or something..
But do some small things like lights, tint(does wonders) and possibly exhaust, give your car a nice sound and look.
Or do the typical springs/shocks.
BUt id go with lights+tint+exhaust
