I had the PPI on my car done 8 years ago with Alpine Autowerks:
4509 1 ST SE
Calgary, Alberta
Canada
Telephone: (403)-287-9114
marc@alpineautowerks.com
Not only did Marc do an excellent PPI, he brokered my purchase as I was out-of-town.
Reasonable price, great communication, right on the money with the PPI. Highly recommended from my anecodotal experience.
