Launched in 2005, the Audi Q7 `4L` was the brand's first full-size SUV and shared its `PL71` technical base with the Volkswagen Touareg. Against the BMW X5, it focused less on agility than on the feel of a large, prestigious family-distance machine, with optional seven seats and a genuine ability to cover miles. The starting point for any serious purchase is simple: a Q7 4L should be bought on maintenance history, not on the badge alone.
The market is dominated by the `3.0 TDI V6`, followed by the `3.6 FSI`, `4.2 FSI` and `4.2 TDI`. All use `quattro` and most came with the `6-speed tiptronic`. The pre-facelift version already carries dense electronics for its era, a lot of weight and a sophisticated chassis that makes it very convincing on the motorway, but far more expensive to catch up than a simpler SUV. Air suspension was not standard everywhere, yet it changes the ownership budget clearly when fitted.
