The best way to buy a car today in the spec you want (this is very important and plays a massive role), is usually to use a comparison/broker site like Carwow or Broadspeed, take up the finance option as they usually tend to have freebies or deposit contributions adding to the total discount, and then paying the whole lot off. VW seem to actively encourage this practice.
Otherwise, if you're not bothered by the spec or which car you want to drive, there are some cracking deals to be had on PCP. Think I saw a very well specced brand new Volvo V90 for £200 a month and a low deposit for 24 months. Was a steal tbh
