I have been involved and made a living with auto and truck repair and modifications since 1968 . I know a thing or 2 about auto and truck repair. I have built many high performance engines ,from Alfa to Chevy ,and pretty much everything in-between. I HS built a 1965 Falcon that was a 12 second street driven car. My last B4 the CX5 was a 2014 Chevy Camaro SS 1 LE heads and cam car I modified that made 482 RWHP on 91 octane pump gas that did 11.56 1/4 times and 1G on a skid pad with street tires , that passed Arizona emissions. The reason I bought the 2023 Mazda cx5 was due to keeping my AZ drivers license and being able to get auto insurance. It looks like I am doomed to drive transportation vehicles ,and drive like the 72 year old old man I am.
Mandated Regen and EGR has made all diesel vehicles less desirable and more problematical.
