Mastria Nissan

I have purchased 3 vehicles from Mastria and all have had numerous problems. I also purchased the extended warranties. The repair shop is very rude and when I brought the my Nissan back after it needed $8000 numerous problems. I also purchased the extended warranties. The repair shop is very rude and when I brought the my Nissan back after it needed $8000 worth of repairs (which I let them do) because it was making unusual sounds and not running right they told me I was hearing things and to not come back for them to run diagnostics any more or they would charge me. I now have a vehicle that the extended warranty is up and we still have the same problems that I spent 8000 dollars to fix. Rude,Unqualified and should be closed down. More
