Should I get this vehicle offered?

I was offered, by my mechanic, a Volkswagen Tiguan Jeep, two-litre Diesel, Automatic, freshly through the MOT and worth Nine Grand.

It's considering carrying my friend's mobility scooter, should we go on an adventure.

How much would she be to insure? I received mixed messages about a Polo having enough room at the back; to carry a mobility scooter.

What do you Chaps think?
