Just a point on the light beige carpets
I've had several company cars with light carpets - a BMW with very light grey carpets and an M class Merc with light beige carpets
Had them both for three years and did around 100K in both sometimes with the family and both carpets looked hardly soiled when I handed them back
And I didn't regularly spot clean them - just hoovered out with a brush attachment every couple of weeks
I think it's a complete misnomer that light carpets spoil quickly
And especially on a Morgan which will be looked after and driven less than a company car
One of my old regulars once took his golden retriever to the local BMW dealer and told them that he wanted a car with an interior which matched his dog's hair.
