Before my Zed I had a 2003 Celica T-Sport from new, did 17k miles in it. They are more refined and smoother than a Zed, something I noticed straight away and the gear box is one of the best on the market for a car of that type. There's no doubt that the Zed's gearchange is not as good, 1st to 2nd is crunchy but the rest of the changes are reasonable. The ride is rougher too and cheapo tyres won't help either. 47k isn't a lot of miles for a Zed, but it depends how it's been driven. You should look out for one of the Zed's on sale right here, that way you'll get to know the history of the car and you can guarantee that it will have been looked after a lot better than an anonymous 47k model from a dealer. In any case, try a few more test drives, some of the guys on here drove loads of them before they found the one they wanted.
