What are people saying about us

Arrived early, packaged perfectly, beautiful model and a very well received gift for my car enthusiast OH he is over the moon with it
- charlibaltimore
This is the 8th model I have built from this company, and once again I'm completely satisfied. It is beautiful and the workmanship is wonderful, I highly recommend it.
- chromebandit
Have build many of these, and for a plastic model, this is one of the best. All parts were included and assembled model runs perfectly. For the price, can't be beat.
- kellyhorne
Very well made and detailed. Instructions were a little to non understandable but made out. Surprised all the parts where there, only the switch hold down but was missing
- TBNWorld
I was looking for something challenging and I didn't want to be able to finish it in a day or two. This was perfect. I worked on it a little here and a little there and it took a few weeks to finish and that was exactly what I wanted this to be.
- sacredcirclegifts
High quality, great instructions and fun to build. It took me a little onger than spec'd but i would not have minded it being even longer. This is my first model. I hope there are comparable projects like this.
- thewiltingwick
Love the V8. I ran in a small issue and contacted consumer services. Very responsive and I am completely satisfied. Looking forward to my next purchase.
- DocDisco81
Bought as a gift for an older gentleman and he loved it..all metal pieces and so easy to put together..the instruction manual was easy to read. Just wish there was more like this.
- janmakuc
Very much fun to build. All metal parts fit precise and the manual has for each building step easy to understand drawings and descriptions. The model engine looks great and also works well.
- graigkarl
It was a present for my brother who graduated in mechanical engineering! He simple loved! It was perfect!
