i`ve built about 26 models and most of them are not complete or there`s glue on most windows i loose some part from the engine so some engines wouldn`t run if real - trouble with the paint - the 2 i did good on were the tractor trailers well there were no trailers but the rig came out good - but all in all - i LOVE IT AND WILL NEVER GIVE UP who knows maybe i`ll get as good as some of you guy`s some day - oh well CARRY ON
