totally different cars, but i dont expect mark was expecting us to say "yeah better then a micra". It's a different car to a micra, insuranec is fairly hefty, group 11 iirc. Thing is, getting pretty rare and expensive for decent ones, what you may for an L reg swift she could have a much newer k11 which could be made into similar power, but there are other alternitives then a k11 as you know.
If she does want one, don't let her rush into the first you find, there's a number of things to check like with any car, find out its common problems, faults and maybe even recalls if they were done.
