@DaveF Wow .... Six month waiting list for your T6, then plus another 5 months. Longest I've heard of anywhere is 3 months. We all like a T6 but they aren't McLaren's or SVO Autobiog's!! Something very strange going on there.
My experience of Leighton is that they will bend over backwards to secure clients at their price point. They are a huge customer of VW (UK). They have 100+ of the highest end new vans in stock at any given time (I've seen them, it looks like more). So, if they don't already have what you want, I just can't see VW messing Leighton around when a customer places a custom spec order.
Shame you had such an odd experience because their after-sales is outstanding as well IMO ........... and by my own admission, I'm OCD about my cars
To be honest I was really disappointed by them at the end - they just couldn't come up with a solution. The real shame was that I really wanted a Leighton van too!!
