Installed a false floor in my Prado 250 gxl 7 seater. Great fit. Easy to install myself. Looks factory fitted. Provides so much more room.
Better than I expected, amazing fit and look.

I have brought many products from this company over the years, mostly from third party suppliers like ARB or TJM & having them fitted by the same company
When it came time to build my new 79 series I already knew what I wanted & where I was going to purchase it
As always the quality of the product is faultless and fitment of my centre console, roof console , door trims & speaker pods was very simple
The improvement to the comfort of the car is extremely impressive & functional

Ordered the premium floor console with scan gauge for my 2024 troopy, excellent fit and build quality is top notch! Should’ve come like this from factory
Quality product. The front mounting doesn't line up easy enough. Hole needs to be in a different position
Exactly as described, fits and works perfectly
