As above, ex lease is different to ex rental. Most company cars have to be serviced properly and staff get a bollocking if they aren't kept in tidy condition. as most have them 2-3 years they are also less likely to kick the balls of the car.
Ex lease, your car for what, a few days a week? rag the tatties off it!!
There will be exceptions to the rules with the odd d*ckhead who rags any car they own, company or privately owned.
My mate got his scirocco from Blackhorse car sales as did my mates dad and both cars had full main dealer service history, well spec'd and in A1 condition and cheap! Neither have given the slightest bother bar the rocco having a sensor pack up, all sorted under the 12 month warranty provided with the car and the work was done by VW main dealers.
If it drives nice and tight, is clean and straight and has a full main dealer history it is as safer bet as any.
