Ah yes never thought about the car itself and I suppose lifting a 150Kg could cause a bit of a strain on something like a city car. ?
With your Touran makes you think they might have already discontinued the model without telling anyone, same sort of thing happened with my KIA Carens when they discontinued it in 2018 and I think my dealer did not even know about it at the time I took delivery and mine is one of the last Carens on the road.
KIA gave the excuse the demand was not strong enough to continue but I think it was more to do with not being able to hit the right numbers to get a WLTP ticket for their 1.7 diesel engine as they stopped making that too at the same time but of course the Touran does have its ticket but maybe there not selling many but more likely could be just a lack of PC chips holding up production and what better way to slow demand by hiking the price a few hundred percent even if its only Motability customers taking the hit.
