I would definitely buy from them again and again. The Mazda Miata was my dream car when it came out in 1990. I finally purchased a used 1991 in 1997, with 27,000 miles on it, one owner car ...
I'm a Miata fan, personally, which makes sense since I own two - a '91 1.6 and an '02 1.8 VVT - but I feel there's one thing missing from the current Miata lineup, and Mazda needs to fix this.
