I'm an "official" tester for a Detailing company that has a shop so tried a few of their products out last night - restored the faded bumper protector, got the tyres back to life, gave the wheels a deep clean, the glass a good polish and so on.
We did consider moving it on for a bit but decided it's too much fun and the kids would be mortified too. Plus we have a month booked off from July 27th in it.
We'll just have to roll with the VW reliability punches… :doh
