I do like my mk3 but i like that jetta of yours too, tough choice.
Looking at your mk3 I would have to say get back on bord lol
i got rid my my black mk3 and regretted it every day. i had a bora and tried a family but i had to sell them and get another mk3. and now i have got a mk3 again i smile everytime i drive it. i realise now no matter what car i get i will always be drawn back to a mk3. iv done it 3 times now and iv learnt my lesson.
