Query: difficult to assemble, poor quality

I never write reviews but was compelled to for this due to its cost andd outrageously poor design. It took two guys (both trained in engineering) 2 days to get assembly right. The instructions were barely helpful. Once built, the front wheels were not parallel and adjustment for this is not possible. So the car looks great but doesn't drive (and when pushed it begins to come apart due to bad design). This is worse than frustrating when your[...]and his friends are dying to use it. Don't go near this product.
