Welcome to the madness, Sampson!
www.cobracountry.com is the go-to place for Cobra replica shopping.
You will not find anything worthwhile for $13.5K, period.
Do some research here and ask a few questions. There is a huge variety in quality, authenticity, specifications, equipment, reputation and value among the many brands of replicas that have been produced over the years.
The right Cobra delivers an experience like no other car can, but its highly advisable to do some homework in order to avoid making a purchase you could end up regretting.
