I avoid using low poly cars unless they really are far from the camera. Even then I use at least 3 materials in the model: body, glass and tyres.
The trouble with the texturing on these lp cars is that the lighting is already baked in and usually they're a single mat which is unrealistic - ie the glass is not transparent and the same mat qualities are used for all parts.
There are a few good car collections around with proper materials or at least good poly/nurb groups so you can assign materials. Dosch Design even have a collection with maxwell mats already setup (although I do my own), it might be worth giving these a go.
Good surfacing on the tarmac and I can see you've put the effort in to avoid textures repeating - but maybe the 'patchiness' needs toning down a wee bit.
thanks Cadhorn - scene at the planning commision: an older lady with red hair and too much perfume says "wait, wait, wait...we didn't approve this... ". she likes to throw her weight around. ha ha.
i agree that a shot with some of the interior modeled would be very nice.
faraz - i've gotten several comments on the cars. these were free from lowpolygon but i'll check out the dosch collections for the next one. thanks.
