The best car I have enjoyed owning was a white Rover 75 estate 2.0d. I loved the wood/leather interior and wheel, the chain driven engine was bullet proof and it was a rare car, in fact I showed it at the NEC once.
Best car I have driven was an Audi A6 that was a “company” car. It was so quick when accelerating and (apparently, someone else was looking at speedo!) I topped 150mph in it. I appreciate it’s not a competition but it was amazing how easily it got there and how steady it was at that speed.
Best Motability car was a BMW 316d estate. I loved that car and wish it was still on the scheme, although in fairness I would struggle now with how low it is.
