Since this thread is getting thicker, I decided to post a more hefty comment/opinion.
I've seen a few importers' cars and their quality, nothing, nothing beats the quality that Paulo (Rydz) imports. In some cases, they might seem more expensive than other importers, but I don't care, that's the extra price, I for example, was willing to pay for a cleaner car. And that's exactly what I got.
Grades do not mean anything to me anymore, after I've seen Grade 3s look better than Grade 4s from somewhere else.
I've seen some Grade 4 cars at other importers in Montreal and Vancouver that look like total sh*t. I've seen about a dozen of Rydz' cars and they were all so mint that I wouldn't even hesitate on purchasing one.
If you're looking for someone who will be upfront with you about his entire importing procedures, always willing to give you the extra mile (even after you purchase the car) and provide you with some of the cleanest stock from Japan, Paulo is the man to see.
I speak with experience. If anyone has questions they do not wish to post, feel free to PM me, I have nothing to hide about my excellent experience with Rydz.
With that in mind, take your time to shop for your S13, don't trust anyone but yourself and your mechanic. Importing a car is not like buying a local car....its a whole different experience on its own. No one knows what it's like until you buy one.
Gd luck.
