2005 Chevrolet Cavalier LS Sport 2dr Coupe (2.2L 4cyl 5M)
As a mechanic myself, I find that is great car small, and maneuverable. For the size it is quite roomy. For the exterior there are not many modifications other then ground effects, as for the engine, limitless like any other Chevy model. As for build quality is ok for the price, but any do it your selfer can easily fix. A quite and smooth ride with great gas mileage. I drove mine home when I went on leave from Virginia to Texas a 22 hour drive under $100. The only trouble I had was my windshield wiper broke during heavy rain. And the headlights were not very bright.
Stronger headlights and get rid of unnecessary plastic parts.
