I recently sent in my CAS due to a no start on a 2011 mini cooper countryman. I was honestly a little skeptical sending in the entire brain to my car through the mail system to a company I never used before. However, it was a Hail Mary option and I am so glad I did it. Very professional, very efficient. I received updates through the process via email. Once repairs were completed, I received a video of proof that my parts were in the test vehicle and the test vehicle started up proper. Was even shown the diagnostic scanner confirming my parts as well as them communicating with the car and zero codes. Once I paid my invoice, I received all my parts in the mail 2 days later, packed very securely. I 100% would use them again.
