The 90PS TwinAir is fine and lots of fun. Has the character that the 1242cc Fire engine lacks (I know, I've got one). The 105 is just a bit more powerful, perhaps too powerful for 875cc. She might want to go to a 500C with full length sunroof. But getting expensive now in comparison to other cars. Though the VW Up is boring to look at, she should try one of them because they are a lot of fun to drive. Maybe a Smart ForFour 90TCe that looks more funky than it drives. Maybe a Citroen C1 1.2 PureTech Airscape with a full length sunroof for the summer.
