Dear UDO
welcome to gt40s.
Where in germany are you located ?
As already pointed out. GT40s are a different breed than cobras.
KVA are told to be the first GT40 replicas produced. Some of the existing Kits are still based on them.
It all depends on your expectations. If you just want a look a like, you may be fine with the KVA.
If you are about performance as well, than you realy want to look more closely to what generation of KVA it is. If it is the first generation ( Ford front axle and Ford rear axle, non GT40 type suspension) than a lot of modification is required to make this car perform well.
If you like, you may give me a call
