I've used JKM a few times now and always excellent service from them so no need to worry there.
Yes, Kate said it's the front wheels that were tracked so shouldn't need to go for anymore alignments.
When I first got the car back it felt like the steering had gone a bit heavy, don't know if it's because I've got used to it or was imagining it but seems to have gone away now. I haven't had a chance to have a proper drive yet but the car certainly seems happier going round corners and in/out of roundabouts, seems to be more 'stable'.
