Well, nothing wrong with the Golf (l just sold our 2012 Polo as the missus wanted a Land Rover, so now she has a 300tdi 90!)
You will need to re calibrate your driving style, for instance 65mph is the ideal motorway cruising speed, but you soon learn to sit back and let the world go by in their fast depreciating tin boxes.
A Defender also takes any aggression you might have out of your driving, and also you tend to get respect from other road users.
l have always been into cars. My other car now is a BMW Z3 3.0 M Sport. Before that l had a Lotus Elise S2, a Ferrari Mondial t, a Porsche 928 S4, and a 1932 Standard Little Nine, in that order.
And now l drive a Defender. So that must say something. The Defender is great fun to drive slowly. The other cars l could never get anywhere near their limits on the road. Well, except the Standard Little Nine...it only had 23bhp lol
The Z3 never comes out of the garage.
