Hi Gary,
Believe those dimensions are accurate – can also slide the middle row a little. Have a 100kg hoist and a large rollator which is easily accommodated. Love the Touran SEL but have ordered an Allspace SEL which is loaded with kit inc elec tailgate and digital dash. £2799 vs £1099 AP 1.5 DSG. However to match the Allspace would cost £5350 in extras. Ouch and no contest. £1700 led lights and £1250 panoramic roof for starters. Boot Is 700 litres but sufficient for me.
