Three part comment:
- Have you considered the Mazda CX-60 PHEV? - slightly larger than the Tiguan, more power (329HP combined) and equivalent toys and equipment CX-60 drive. I've just had a confirmed build date in July from Mazda, which equates with August/early September delivery. I've no idea what date they would give you if you ordered today.
- My Tiguan PHEV order, with lots of options, is build week 49 (early December). I asked my VW dealer where I stood with cancellation and he said I could cancel any time before build, and even after build they would have no problem selling it as a cancelled order. I've left the order in place in case there is a disaster with the Mazda delivery.
- Before I ordered the VW I nearly placed an order for the Volvo XC-40, but at the time they just dropped a number of driver assistance features, which I considered non-negotiable. I would check if you would be getting the features you want. Of course, if I had been more flexible I would be driving a Volvo now.
