They are very well engineered cars. I spent nearly four years of evenings/ weekends building mine. I sold it to a dealer last summer, here is a link to view the car and see the build quality! This factor can vary according to whether the builder is a perfectionist or not!!!!

What design is the suspension , hopefully wishbones not cart springs or the handling will be suffering , especially with a v8 up front. Some of the cars have 5.7 litre v8's which sounds exciting along with the Healey shape which is great !
