I had the misfortune to be IN a Hyundai i20 recently with my sister - just her and I. Now, I am a big guy, but my sister is a waif.
We went to the bottom of a hill to inspect a house she wanted to buy. Going DOWN the hill was fine. Coming back up was a laugh! I don't think it got out of first gear!
I suppose these cars are fine for city and town, but subject them to a 4% slope and it's game over. I now perfectly understand these old people in these cars - I always thought they were just being old biddies - truth be told the car just ain't cutting it
