The missus had the same problem once when she used my Rover 75 to go shopping instead of her VW Polo. She tried to back into a space into which the Polo would normally fit but ended up bouncing off the car behind her while the front of the Rover was still in the road!
Only thing is, touch parking in the 135 just isn't as forgiving as it used to be - even with them new straw blades!
