As you know, recently I bought an offside window for my T5 to replace the original. Having previously done this for the near side. The window I fitted on the nearside was faultless! Slightly suprising, but REALLY good! No distortions at all. The Offside window is not great! I have sat and thought about it for a couple off weeks so as to give a clear opinion of its problems. They are as follows. The glass is waney, most noticeable at the corners of the apeture. This in itself is an acceptable flaw in a cheap window, however the positioning of the apeture is inaccurate. Slightly tilted down at the front edge, it gives added emphaisis to the glass distortion at the corners. It looks wrong. In comparison to my other window and other vans around where I live, it is not a good example of a sliding window and looks poorly made and finished! It will not take much I think, before it starts to leak. There are other cosmetic issues with it, but as I have said irrelevant until you compare it with the nearside window. The makers name for the nearside is BTO (Turkisk) and the offside window is TVW. Compared to the BTO window it is VERY second rate.
